This circuit contains a 5 Ω resistor in series with two resistors, 6 Ω and 4 Ω, which are in parallel. Start by calculating the combined resistance of the two parallel resistors.

Everything CCEA students need to know about how to conduct an investigation into the resistance of a metallic conductor.

We’ll explain how to calculate resistance using the formula R=IV , where R is resistance, V is voltage, and I is current, and show how this simple equation helps us understand how resistors ...
