In the given circuit, assuming point A to be at zero potential, use Kirchhoff's rules to determine the potential at point B. |
Answer» SOLUTION : USING Kirchhoff.s first rule, we find that current FLOWING in branch DC is 1 A from D to C. Now, APPLYING Kirchhoff.s second rule to the circuit ACDB, we have `V_A + 1+1 xx 2 -2 = V_B` `V_B = V_A + 1` But `V_A = 0` volt , hence `V_B = 0 + 1 = 1V` |
