Question

As shown in the figure, the emf of the cell is 5 V
and the internal resistance of the cell is zero.
The reading of the ideal voltmeter is
5 V
W
10 22
30 Ω​

Answer 1

Answer:

Ideal reading of voltmeter = 5V

Explanation:

Given:

emf = 5V

r [ internal resistance ] = zero

• For ideal voltmeter/battery

                 emf = V

         i = emf/r+R

     as, internal resistance is zero

          i will be zero

therefore, V = 5V
