Question
A candidate connects a moving coil ammeter 
and a moving coil voltmeter 
and a resistance R as shown in figure
If the voltmeter reads 20 V and the ammeter reads 
is
- Equal to 5
- Greater than 5
- Less than 5
- Greater or less than 5
depending upon its material
depending upon its material
The correct answer is: Greater than 5
Here, 
Volt; so,
Since, voltmeter is connected in parallel with resistance 
the effective resistance of this combination is 5 only if the resistance R is greater than 5, since total resistance in parallel combination becomes less than individual resistance
