Q1: To find the current in a 20 Ω resistance connected in a circuit, Norton's theorem is used. IN = 7.5 A. The current though 20 Ω resistance.

A is 7.5 A

B is less than 7.5 A

C may be 7.5 A or less

D may be 7.5 A or more or less

ANS:B - is less than 7.5 A

Norton's equivalent is as shown in figure. Some current will flow through RN. There-fore, current through 20Ω resistance is less than 7.5 A.
