Question

For the circuit shown in figure. The Norton equivalent source current value is_____A and its resistance is_____ Ohms.

• A. $4.5A,2\Omega$
• B. $3A,4.5\Omega$
• C. $2A,4.5\Omega$
• D. $2A,2\Omega$

Answer 1

The correct option is C $2A,4.5\Omega$



Using source transformation



Using source transformation



$I_{sc}=\frac{3+6}{1.5+3}=2A$

$R_N=1.5+3=4.5\Omega$
