Question

Calculate the charge on the capacitor in coulombs if a 20-F capacitor has a 30-V potential difference across it.

• A. $6.7\times {10}^{-7}$ C
• B. $6.0\times {10}^{-4}$ C
• C. 1.5 C
• D. $6.0\times {10}^2$ C
• E. $1.5\times {10}^6$ C

Answer 1

Answer: (D)

$6.0\times {10}^2$ C

Given : $C=20$ Farad $V=30$ volts

$\therefore$ Charge on the capacitor $Q=CV=20\times 30=600$ Coulomb
