Q.  Calculate the value of Current I passed through the circuit.

Solution:

             In the given circuit 2kW & 3kW are in series therefore, the joint effect will be=2k + 3k = 5kW

            To calculate current which is passing through 5k W RESISTOR?

The current flowing through 5kW resistor, through Ohm's law     

                                                             I=V/R

                                                              =10/5k

                                                             =2 mA            Ans.
