Current electricity

Medium

In the circuit shown, the reading of the high-resistance voltmeter when the switch is open is $V$ .

Circuit diagram

When the switch is closed, the reading becomes $58V\displaystyle \frac{5}{8}V$ .

What is the internal resistance of the cell?

$Ω5.6\ \Omega$

$Ω24.0\ \Omega$

$Ω9.0\ \Omega$

$Ω25.0\ \Omega$
