4.2.1.3 · Resistance & V = IR
What is the equation linking potential difference, current and resistance? Give units.
Show the answerHide the answer
V = IR. Potential difference (V) = current (A) × resistance (Ω).
4.2.2 · Series & Parallel Circuits
What are the rules for current and pd in a series circuit?
Show the answerHide the answer
Current is the same through each component. The total pd of the supply is shared between the components.
4.2.4.1–4.2.4.2 · Electrical Power & Energy
What are the two equations for electrical power?
Show the answerHide the answer
P = VI (power = pd × current) and P = I²R (power = current² × resistance).
