What are the rules for series and parallel circuits?

A Parallel circuit has certain characteristics and basic rules: A parallel circuit has two or more paths for current to flow through. 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.
A.

How does voltage work in a series circuit?

In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
  • What is the voltage in a circuit?

    Defined in these scientific terms, 1 volt is equal to 1 joule of electric potential energy per (divided by) 1 coulomb of charge. Thus, a 9 volt battery releases 9 joules of energy for every coulomb of electrons moved through a circuit.
  • What are the rules for resistance in a series circuit?

    Resistor in series. When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. The total resistance of a number of resistors in series is equal to the sum of all the individual resistances.
  • What is the difference between a series and a parallel circuit?

    In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
B.

What are the rules for resistance in a series circuit?

Resistor in series. When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. The total resistance of a number of resistors in series is equal to the sum of all the individual resistances.
  • What is the definition of a series circuit?

    A series circuit is a closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths. In a series circuit, the current through each load is the same and the total voltage across the circuit is the sum of the voltages across each load.
  • What is the potential difference in a series circuit?

    Two identical resistors connected in series will share the potential difference. They will get half each. For example if two identical resistors are connected in series to a 3 V cell then the potential difference across each of them is 1.5 V.
  • What is the Ohm's law?

    The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R. Ohm's Law is given by: V = I R where V is the potential difference between two points which include a resistance R.
