Calculate the drop voltage for a battery of internal resistance 2 ohm and emf of 24 volt When connected to external resistance of 158 ohm.

The drop voltage is 0.3 V

Explanation:

Electromotive Force EMF

When connecting a battery of internal resistance Ri and EMF ε to an external resistance Re, the current through the circuit is:

The battery has an internal resistance of Ro=2 Ω, ε=24 V and is connected to an external resistance of Re=158 Ω. Thus, the current is:

i = 0.15 A

The drop voltage is the voltage of the internal resistance:

The drop voltage is 0.3 V

the answer to this is proletariats.

hope this : )

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
