Learn how to calculate resistance in series and parallel circuits. ... Calculate the total resistance of the circuit. Calculate the current flowing in the \({3}\Omega\) resistor.

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 ...

Since you know the resistance of, and voltage across, each resistor, you just use Ohm's Law again to calculate the current through each wire. The 17 Ohm resistor, with a voltage drop of 7 Volts ...
