Divide 40va by

**24**volts gives you**1.6666667 amps**or rounded**1.7 amps**.What does the VA stand for on a transformer?

A volt-ampere (

**VA**)**is the**unit used for the apparent power in an electrical circuit, equal to the product of root-**mean**-square (RMS) voltage and RMS current. In direct current (DC) circuits, this product is equal to the real power (active power) in watts.1

## How many volts is a 20 amp?

20 AMPS x

**120 volts**= 2400 watts. As you know by now, you can only load up to 80% of the stated rating. What can I plug into a 20 AMP circuit? A 20 amp circuit at**120 volt**(80%) will hold 1920 watts.2

## What does VAC mean on a transformer?

In a DC circuit, this would be given as 40W (Watts). However, with AC, the

**voltage and current**waveforms can be shifted in relation to each other. This causes a difference between the "real power" and the "apparent power". It is customary to give the apparent power rating of a transformer in VA (Volt-Amps)3

## How many amps are used in a defibrillator?

This shock is administered by a device called a defibrillator. These defibrillators range in the amount of shocks they can administer. From the discrepancies in the research, there does not seem to be an universal amount that will revive a heart. The voltages can range from 200 to

**1,700 volts**.4

## Is Va the same as Watts?

The power in

**watts**is the real power drawn by the equipment. Volt-amps are called the "apparent power" and are the product of the voltage applied to the equipment times the current drawn by the equipment. Both**watt**and**VA**ratings have a use and purpose. The**VA**rating is used for sizing wiring and circuit breakers.5

## How many amps are in a 120 volt?

The label or manual will show the input voltage (110, 120, 220,

**240**; written as: 120 volts, 120V, 120 volts AC, or 120VAC), the wattage (written: 100 Watts or 100W) or the amperage (0.5 Amps, 0.5A or 500mA).6

## What is line to line voltage?

Three-phase “Y” connection has three

**voltage**sources connected to a common point.**Line voltage**refers to the amount of**voltage**measured between any two**line**conductors in a balanced three-phase system. With the above circuit, the**line voltage**is roughly 208 volts.7

## What is meant by KVA?

A

**KVA**is simply 1,000 volt amps. A volt is electrical pressure. An amp is electrical current. A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps. The power factor is a ratio (a number from 0 to 1) of real power and apparent power.8

## What is the meaning of VAC in electrical?

There is no such thing as

**VAC**power - it is just AC power. When you see 110**VAC**on an appliance, it means 110 volts AC power. Voltage is a measure of "circuit pressure." It refers to how hard the**electricity**pushes through a circuit.9

## What is the amperage of a car battery?

An average car battery has a capacity of around

**48 amp hours**which means that, fully charged, it delivers**1 amp**for 48 hours,**2 amps**for 24 hours, 8 amps for 6 hours and so on.10

## How do you calculate amps?

The formula for Volts is Watts divided by

**Amps**. To use the chart, cover up the V with your finger and use the remaining chart**calculation**of W divided by A. Using our sample panel data, 60 watts divided 5**Amps**equals 12 Volts. The formula for**Amps**is Watts divided by Volts.11

## What do you mean by apparent power?

In an AC circuit, the product of the rms voltage and the rms current is called

**apparent power**. When the impedance is a pure resistance, the**apparent power**is the same as the true**power**. But when reactance exists, the**apparent power**is greater than the true**power**.12

## How many amps is 500w?

For AC power supply, amps are equal to watts divided by power factor times volts. amps = watts / (PF × volts)

For resistive load without inductors or capacitors, the power factor is equal to 1:

amps = 500W / (1 × 120V) =

For resistive load without inductors or capacitors, the power factor is equal to 1:

amps = 500W / (1 × 120V) =

**4.167**A.13

## What is 1000 watts in amps?

To provide that

**power**at a lower**voltage**you increase the current (or vice versa).**Power**is**voltage**multiplied by current. 1000 Watts can be 250**volts**RMS AC x 4 amps (i.e. 250 x 4 = 1000). 1000 Watts can be 12**volts**DC x 83.3 amps (i.e. 12 * 83.3 = 1000).14

## How many watts is 1.5 amps?

The conversion of Volts to Watts at fixed amperage is governed by the equation Watts = Amps x Volts.

For example 1.5 amps *

Converting Volts to Amps at fixed wattage.

The conversion of Volts to Amps if the wattage is known is governed by the equations Amps = Watts/Volts.

For example 1.5 amps *

**12**volts =**18 watts**.Converting Volts to Amps at fixed wattage.

The conversion of Volts to Amps if the wattage is known is governed by the equations Amps = Watts/Volts.

## How many amps is 4500 watts at 240 volts?

Since this is a purely resistive load 5500 watts at 240 volts is

**23 amps**, breaker is sized at**30 amps**and 10 awg wiring is used. In your case if the elements are strapped for 4500 watts draw is**18.75 amps**, permanent draw loads should be sized at 80% of breaker capacity so a**20 amp**breaker is limited to**16 amps**.16

## Are electric water heaters 120 or 240?

Most residential

**electric water heaters**use**240**volts. Their are single element**water heaters**that operate on**120**volts and single element**water heaters**that operate on**240**volts. Check the label on your**water heater**for the voltage rating. Breakers are usually labeled, however, they can be labeled wrong.17

## What size breaker is needed for a hot water heater?

A

**water heater**of this type is required to be considered a continuous load meaning that the branch circuit needs to be calculated at 125% of the**heater's**rated ampacity. 4500/240 = 18.75 amps, will work on a 20 amp OCPD but, 18.75*125% = 23.4 amps, requires a 25 or 30 amp circuit.18

## How many amps is a 50 gallon water heater?

Most 50 amp water heater will come with 4500 watt elements. On a

**240**volt circuit that is**4500 / 240**=**18.75 amps**, so, no, that will not trip a**20 amp**breakers, however, it will be operating the breaker nearly 95% of its 20 ampacity rating and most breakers are not rated for that.19

## How many amps do I need for a stove?

Since stoves generally draw from

**40**to**50 amps**, it is permissible to wire them with 8-gauge wire. If your stove draws**50 amps**, however, you will ensure adequate power to the stove and avoid the danger of overheated wires by using 6-gauge wire. You must use 6-gauge wire if your stove is rated for more than**50 amps**.
