Question

What charge is stored in a 180μF capacitor when 120 V is applied to it? Hint: Farad is the large unit; usually capacitors comes in micro (10⁻⁶) Farad or in Pico (10⁻¹²) Farad

a. 21.6C
b. 21.6mC
c. 21.6μC
d. 2.16C
e. 2.16μC
f. 0.216μC

Answer 1

The charge stored in a 180μF capacitor when 120V is applied to it is calculated using the formula Q = C × V, resulting in a charge of 21.6mC.

Step-by-step explanation:

The charge (Q) stored in a capacitor can be calculated using the formula Q = C × V, where C is the capacitance in farads and V is the voltage in volts. For a 180μF (or 180 × 10−6 F) capacitor with a voltage of 120V applied to it, the charge stored is:

Q = 180 × 10−6 F × 120 V = 21.6 × 10−3 C = 21.6 mC

Therefore, the correct answer is b. 21.6mC.
