How do you read the value of a resistor?

Steps

Position the resistor with the gold or silver color band to the right..
Read the color sequence that must be decoded to determine resistance.
Determine the coded number for the resistive value.
Determine the tolerance of the resistor.
Determine the decoded number for the resistive value.

Similarly, you may ask, which direction does a resistor go?

If I understand your question, then yes - resistors are reversible, in the sense that they can be connected to the circuit in either direction. Resistors are not like diodes or capacitors. They do not have a polarity. The conduct (or resist) current equally in both directions of current flow.

How do you check a resistor with a multimeter?

Steps

Remove power from the circuit containing the resistor.
Isolate the resistor from the circuit.
Inspect the resistor.
Read the resistor value visually.
Prepare a digital multimeter (DMM) to measure the resistor.
Measure the resistance.
Determine the actual resistance of the resistor.

Do resistors have a positive and negative side?

Current in the drawing above is shown entering the + side of the resistor. Resistors don't care which leg is connected to positive or negative. The + means where the positive or red probe of the volt meter is to be placed in order to get a positive reading. This is called the "positive charge" flow sign convention.

What is the value of the resistor?

A resistor is a device that opposes the flow of electrical current. The bigger the value of a resistor the more it opposes the current flow. The value of a resistor is given in ohms and is often referred to as its 'resistance'.

What are the colors of resistors?

Components and wires are coded with colors to identify their value and function. The colors brown, red, green, blue, and violet are used as tolerance codes on 5-band resistors only. All 5-band resistors use a colored tolerance band.

What is a resistor color code?

An electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables.

What is equivalent resistance in a parallel circuit?

Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +

What is a resistor made up of?

Resistor composition. Resistors can be constructed out of a variety of materials. Most common, modern resistors are made out of either a carbon, metal, or metal-oxide film. In these resistors, a thin film of conductive (though still resistive) material is wrapped in a helix around and covered by an insulating material.

What is meant by the tolerance of a resistor?

"Tolerance is the percentage of error in the resistor's resistance, or how much more or less you can expect a resistor's actual measured resistance to be from its stated resistance. A gold tolerance band is 5%tolerance, silver is 10%, and no band at all would mean a 20% tolerance." Source: Resistor Color Codes.

Why are some resistors blue?

The beige-colored body of a resistor is often an indication that its tolerance is 5%, while a blue-colored body often indicates a tolerance of 1% or 2%. The blue-bodied resistors and the dark brown resistor contain metal-oxide film elements, while the beige-bodied resistors and the green resistor contain carbon film.

What is a resistor and what does it do?

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

How do you read a capacitor?

Method 2 Reading Compact Capacitor Codes

Write down the first two digits of the capacitance.
Use the third digit as a zero multiplier.
Work out the capacitance units from context.
Read codes that contain letters instead.
Read the tolerance code on ceramic capacitors.
Read letter-number-letter tolerance values.

Can I test a resistor in circuit?

Turn the multimeter dial to the resistance setting. Power off the circuit containing the resistor you wish to measure. Never measure a resistor in a circuit with a live current running through it. A bad resistor will either show infinite resistance or a measurement far higher than its rated resistance.
