Expert Solution
Step 1

To solve the above problem, we will use Ohm's law and Kirchhoff's law. Ohm's law states that the current flowing in a conductor is directly proportional to the voltage applied across it when other parameters like temperature are kept constant.

i.e., V = I×R

Kirchhoff’s laws:
KCL: It states that at any node the sum of incoming and outgoing current is always zero or we can also say at any node the sum of the incoming current is equal to the outgoing current.
KVL: It states that in any mesh the sum voltages applied and the voltage drop are always zero or we can say that the sum of voltages in a closed loop is always zero.
