In this question, there is a load resistance.
00:04
This load resistance is connected to the battery.
00:08
This is internal resistance.
00:10
Small r.
00:11
Emf.
00:12
This is capital r.
00:14
This is the applied voltage.
00:16
V here.
00:17
So applied voltage is equal to this is also called terminal voltage.
00:22
And the emf is equal to 20 volts.
00:27
The current is flowing from the battery that is equal to 2 ampers.
00:32
So resistance resistance is not given here.
00:38
So we are calculated internal resistance and external resistance.
00:42
Internal resistance and external resistance.
00:46
So first of all, we are calculated the internal resistance.
00:51
Emf is equal to terminal voltage plus current times internal resistance...
