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 ...

This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t ...

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.
