Question

the reading of an ideal voltmeter (v) connected across the resistance R in the circuit as shown is a )3V B) 2v C )4 V d)1v.





please answer the question please please please please please​

Answer 1

Answer: c) 4v

V=IxR

=0.02x200

=4

Answer 2

Answer would be c) 4V

Ohm’s law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit.

The formula for Ohm’s law is V=IR.

Voltage = Current× Resistance

here according to the question

I = 0.02 Amp

R = 200 Ohm

V= 0.02 × 200 = 4 v
