Two capacitors, each of capacitance 2μF are connected in parallel. If the p.d across them is 120V, calculate the charge on each capacitor
6.0 x 10-5C
1.2 x 10-4C
2.4 x 10-4C
4.8 x 10-4C
Correct answer is C
C = C1+C2=2+2=4μF
but Q = CV
= 4 x 10−6 x 120
= 4.8 x 10−4
∴ Each of the capacitor has a charge of \frac{4.8 \times 10^{-4}}{2}
= 2.4 x 10^{-4} C
