Question

In the given figure, an ammeter is put to measure the current through the resistor and a voltmeter to measure the voltage across the 12 ohm resistor. Note down the reading in the ammeter and the voltmeter.

Answer 1

Answer:

Explanation:

The switch is open so both will be 0.

But if we close the switch:-

I=V/R = 8/25 = 0.32 A

so ammeter will show 0.32 A

Now we have to calculate the PD for 12 ohm resistor.

Since current remains same for series circuit, I=0.32 A

V=IR

so V= 0.32 x 12 = 3.84 volts

therefore voltmeter will show 3.84V

Hope my answer is correct
