Solution
An ammeter and a voltmeter are connected in series to a battery. Their readings are noted as ‘A’ and ‘V’ respectively. If a resistor is connected in parallel with the voltmeter, then both A and V will decrease.
Explanation:
When a resistor is connected in parallel, the overall resistance of the circuit decreases. Therefore, current will rise, but voltage will diminish due to low resistance.
