Question

Find $V_A-V_B$ for the given network ?

• A. $11\text{V}$
• B. $-22\text{V}$
• C. $22\text{V}$
• D. $55\text{V}$

Answer 1

The correct option is C $22\text{V}$


Using KVL to the given network we get,

$V_A-\frac{Ldi}{dt}-iR-10=V_B$

$V_A-(2\times 3)-(2\times 3)-10=V_B$

$V_A-6-6-10=V_B$

$V_A-V_B=22\text{V}$
