An ammeter and a voltmeter are joined in series to a cell. Their readings are A and V respectively. If a
resistance is now joined in parallel with the voltmeter.
Both A and V will increase.
A will decrease, V will increase.
A will increase, V will decrease.
Both A and V will decrease.

Answer:
When a resistance joined in parallel , the effective resistance of the circuit will reduce.
Thus, current will increase and voltage will decrease being low resistance.
