      A parallel configuration of resistors, however, allows multiple paths for the charge to travel throughout the circuit. The resistors in the circuit shown on the right are in a parallel configuration, and the voltage will remain the same across each resistor. The current will change. The equivalent resistance is calculated using the

      A parallel circuit has at least one point where the circuit divides, creating more than one path for current. Each path is called a branch. The current through a branch is called branch current. If current flows into a branch in a circuit, the same amount of current must flow out again, This rule is known as Kirchoff’s current law.

      A series-parallel circuit, or combination circuit, combines both series and parallel connections. Most electronic circuits fall into this category. Series-parallel circuits are typically used when different voltage and current values are required from the same voltage source. Series components form a series string. Parallel components form a ...

      Individual voltages throughout the circuit add up to the total voltage. Resistance in parallel There are many different ways to organize a parallel circuit. In the practical world, most of the wiring is done in parallel so that the voltage to any one part of the network is the same as the voltage supplied to any other part of it.

      The current in a parallel circuit equals the voltage applied across the circuit divided by the resistance between the two points where the voltage is applied. Each path for current in a parallel circuit is called a branch. Each branch current equals V/R where V is the same across all branches.

      When current enters a node (junction) it divides into currents with values that are inversely proportional to the resistance values. The most widely used formula for the current divider is the two-resistor equation. For resistors R 1 and R 2, Notice the subscripts. The resistor in the numerator is not the same as the one for which current is found.
