Question

in a circuit with 72 volt batteries there are resistors of 6 kilo ohm ,4 kilo ohm , 3 kilo ohm and 2 kilo ohm.find current passed through 2 kilo ohm resistor​

Answer 1

I hope you meant all the resistors are in series, in that case, the answer is 4.8mA.

And if it was in parallel then it would be 36mA.
