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 voltmenter, ….. options a) A will increase, V will decrease b) both A and V will increase c) both A and V will decrease d) A will decrease, V will increase

Answer:
on connecting a resistor in parallel to a well known circuit equivalent resistance including internal resistance of cell or battery and new resistor decreases which increases current in the circuit and reading of ammeter increases.
At the same time potential difference across ammeter increases so for a constant emf source reading of voltmeter should decrease.
