A handy nomograph quickly determines the equivalent resistance of two parallel resistors. Although you could use the standard formula and a calculator, the nomograph also lets you easily find ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. In other words the currents in the branches of a parallel circuit add up to the ...
