An ammeter and a voltmeter are joined in series
\( \mathrm{P} \) to a cell. Their readings are \( A \) and \( V \) respectively.

W If a resistance is now joined in parallel with the voltmeter
(1) both A and V will decrease
(2) both \( \mathrm{A} \) and \( \mathrm{V} \) will increase
(3) A will increase, \( V \) will decrease
(4) A will decrease, \( \mathrm{V} \) will increase
