Sample questions
01What is the formula for Ohm's Law?
- A.I = V × R
- B.V = I × R
- C.R = V × I
- D.P = I × R
Why: Ohm's Law states that V = I × R, where V is voltage in volts, I is current in amps, and R is resistance in ohms.
02A circuit has a resistance of 20Ω and draws 5A. What is the voltage?
- A.25V
- B.15V
- C.4V
- D.100V
Why: Using V = I × R: V = 5A × 20Ω = 100V
03What is the current through a 50Ω resistor connected to 230V?
- A.11,500A
- B.4.6A
- C.280A
- D.0.22A
Why: Using I = V/R: I = 230V ÷ 50Ω = 4.6A
FAQ
Is the Level 3 Electrical Science mock exam free?
Yes — 100% free, no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.
Can I retake the mock exam?
Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.
Does this count towards the real qualification?
No — this is independent practice material. To gain the actual qualification you need to sit the official assessment through an approved provider.
