Networks Analysis and Synthesis

Q1:
The current source in figure, can be replaced by

A a voltage source of 20 V in series with 5 ohm resistance

B a voltage source of 16 V in series with 4 ohm resistance

C a voltage source of 20 V in series with 4 Ω resistance

D a voltage source of 16 V in series with 5 Ω resistance

ANS:B - a voltage source of 16 V in series with 4 ohm resistance

The parallel combination of 20 Ω and 5 Ω is 4 Ω. Therefore, strength of current source is 4 x 4 = 16 A and source resistance is 4 ohms.
