Question

What will be change in reading of voltmeter when reading in ammeter increase?

Answer 1

{ Voltmeter : Increases (^) }

Justification of the answer;

• According to Ohm's Law ;. 'The potential difference across two ends of a current carrying conductor is directly proportional to the intensity of current flowing through it, provided at constant Temperature.'

• I.e, V= I×R

• Since potential difference across the two ends of a conductor is directly proportional to the intensity of current flowing through it ,it is clear that whenever the intensity of Current Increases the voltage increases too or vice versa.

Answer 2

reading in voltmeter increases^...
because we know V=IR.
where I=current A
so V~I
