Question

an ammeter and voltmeter are shown in series to a cell their readings R and B respectively if a distance are joined in parallel with the voltmeter​

Answer 1

Explanation:

When a resistance is joined in parallel with a voltmeter, the net resistance of the circuit decreases,

hence the current increases.

The potential difference across the ammeter increases (due to more current) and hence,

potential difference across the voltmeter decreases (source EMF is constant).

Answer 2

Explanation:

An ammeter and a voltmeter are joined in series to a battery. Their readings are A and V respectively. If a resistance is now joined in parallel with the ...
