We can use Ohm's Law to solve this problem. Ohm's Law states that the current in a circuit is equal to the voltage divided by the resistance.
In this circuit, the total resistance (external + internal) is:
R = 3ohm + 1.5ohm = 4.5ohm
The voltage across the external resistance is equal to the battery voltage:
V = 12volts
Using Ohm's Law we can calculate the current:
I = V/R = 12volts / 4.5ohm = 2.67Amps
Therefore, the current flowing in the circuit is 2.67Amps.
A battery of e.m.f 12volts and internal resistor r=1.5 ohm is connected to an external resistance of 3ohm calculate the current flowing in the circuit
