Type 3: Numericals

1. Q) A capacitor of capacitance 10 μF is charged to a potential difference of 5 V. Calculate the charge stored in the capacitor.
   Use the formula: Q=CVQ = CVQ=CV.

Solution:

Q=10×10−6×5=50×10−6 C=50 μCQ = 10 times 10^{-6} times 5 = 50 times 10^{-6} text{C} = 50 mutext{C}Q=10×10−6×5=50×10−6 C=50 μC

2. Q) Calculate the energy stored in an inductor of inductance 2 H carrying a current of 3 A.
   Use the formula: E=12LI2E = frac{1}{2}LI^2E=21​LI2.

Solution:

E=12×2×32=12×2×9=9 JE = frac{1}{2} times 2 times 3^2 = frac{1}{2} times 2 times 9 = 9 text{J}E=21​×2×32=21​×2×9=9 J
