Question: If V<sub>A</sub> –V<sub>B</sub> = 10V, then the value of V<sub>A</sub> –V<sub>C</sub> is –...

If VA –VB = 10V, then the value of VA –VC is –

A

(a) 25 V

A

(b) –25 V

A

(c) 10 V

A

(d) 30 V

Explanation

Solution

(a)

VA−10+Q2−20+Q2+10=VB\mathrm { V } _ { \mathrm { A } } - 10 + \frac { \mathrm { Q } } { 2 } - 20 + \frac { \mathrm { Q } } { 2 } + 10 = \mathrm { V } _ { \mathrm { B } }

\ Q = 10mC

Now VA – 10 + V
