1
Which symbol represents an ammeter?
Answer & explanation
Correct: option B
Ammeter = circle with A; voltmeter = circle with V.
2
Where must a voltmeter be connected?
Answer & explanation
Correct: option B
Voltmeters measure p.d. between two points — they go across (parallel to) the component.
3
How many cells are in a 'battery' as shown by AQA's circuit symbol?
Answer & explanation
Correct: option B
A battery is two or more cells joined together.
4
Which component allows current to flow in ONLY ONE direction?
Answer & explanation
Correct: option C
Diodes are one-way — current can only flow from anode to cathode.
5
An LDR's resistance changes with:
Answer & explanation
Correct: option C
LDR = light-dependent resistor. Higher light → lower resistance.
6
A thermistor's resistance changes with:
Answer & explanation
Correct: option B
Higher temperature → lower resistance for a typical NTC thermistor.
