Answer 1

Correct option is (b) 2.83 V Easy explanation: Here all the resistors are connected in parallel and let the voltage be V. Hence, i15=V/15, i5=V/5, i2=V/2, i1=V/1. By kirchhoff’s current law, V/15 + V/5 + V/2 V/1 +5 = 10. On solving equation, we obtain the value of V. As all resistors are in parallel, voltage across each is same as V.
