A battery with 10V emf and 3 internal resistance is connected to a resistor with current 0.5A.What is the terminal voltage when the circuit is closed?

When current is drawn from a cell, the potential difference between a cell’s electrodes, when current is drawn is known as its Terminal Voltage. As per the given question, the following can be expressed:

The E.M.F of battery = 10 V
The internal resistance, r = 3 $\Omega$
Current, I = 0.5A
Resistance = R

According to Ohm’s law, we can obtain:

$I = {{E} \over (R + r)}$

Therefore, R = 17 $\Omega$

Terminal voltage of resistor = V

Now, as per what Ohm’s Law specifies,

V = I $\times$ R

Hence, Voltage, V = 8.5 V
