Simplified Formulas for Parallel Circuit Resistance Calculations

Total resistance of equal resistors in a parallel circuit is equal to the resistance of one resistor divided by the

Total resistance in a parallel circuit can be found by applying Ohm’s Law. Divide the voltage across the parallel resistance

The sum of the currents flowing through each branch of a parallel circuit is equal to the total current flow

The total resistance in a series circuit is equal to the sum of all the parts of that circuit, as

Parallel circuits are those circuits which have two or more components connected across the same voltage source (Figure 17). Resistors

A series circuit is a circuit where there is only one path for current flow. In a series circuit (Figure

Each electrical circuit has at least four basic parts: a source of electromotive force, conductors, load or loads, and some

Resistivity is defined as the measure of the resistance a material imposes on current flow. The resistance of a given

A wiring diagram is a very simple way to show wiring connections in an easy-to-follow manner. These types of diagrams

A block diagram is used to show the relationship between component groups, or stages in a circuit. In block form,
