Question

Calculate the current drawn from the battery in the given network shown here. state kirchhoff's loop law and name the law on which it is based on.

Answer 1

Explanation:

The given circuit is an example of wheatstone bridge. Its equivalent resistance R is given by 1/.R = 1/(1+2) + 1/(2+4) = ½. Hence R = 2 ohm. The current drawn is (4V/ 2ohm)= 2 Ampere. It is an example of KCL (Kirchhoff’s Current Law). According to the law, the algebraic sum of all the currents entering and leaving a junction should be equal to 0.
