Question

If the total charge stored in capacitors is equal to 100μc, then find the value of x. (10V)

Answer 1

Therefore, The value of x is 5

Charge on C1 is Q1=2$\times$10=20$\mu$C

Charge on C2 is Q2=$x\times$10=10$x\mu$C

Charge on C3 is Q3=3$\times$10=30$\mu$C

Total charge 20+10$x$+30=100

$\Rightarrow$ x = 5
