a) 1.93 V
b) 2.83 V
c) 3.5 V
d) 5.7 V
View Answer
Answer: b
Explanation: Here all the resistors are
connected in parallel and let the voltage be V.
Hence, i15=V/15, is=V/5, iz=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.
