A capacitor of capacity `10muF` is subjected to charge by a battery of 10 V. Calculate the energy stored in the capacitor.A. `2xx10^(-7)J`B. `3xx10^(-5)J`C. `5xx10^(-4)J`D. `8xx10^(-6)J` |
Answer» Correct Answer - C Given, capacity, `C=10muF=10xx10^(-6)F` Voltage, V = 10 V, Energy, E = ? Energy stored in the capacitor, `E=1//2CV^(2)` Now, put the values and calculate the required energy of capacitor. `E=(1)/(2)CV^(2)=(1)/(2)xx10xx10^(-6)xx10xx10` `E=5xx10^(-4)J` |
