Question: The energy stored in a capacitor is given by which of the following formulas? (2021)

Options:

Correct Answer: 1/2 CV^2

Exam Year: 2021

Solution:

The energy (U) stored in a capacitor is given by the formula U = 1/2 CV^2, where C is capacitance and V is voltage.

The energy stored in a capacitor is given by which of the following formulas? (2021)

The energy stored in a capacitor is given by which of the following formulas? (2021)

Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy.
Step 2: Know the symbols used in the formula. 'U' represents the energy stored, 'C' represents capacitance, and 'V' represents voltage.
Step 3: Learn the formula for energy stored in a capacitor. The formula is U = 1/2 CV^2.
Step 4: Break down the formula. This means you take the capacitance (C) and multiply it by the square of the voltage (V^2), then multiply that result by 1/2.
Step 5: Remember that capacitance is measured in farads (F) and voltage is measured in volts (V).

Capacitance – Capacitance (C) is the ability of a capacitor to store charge per unit voltage.
Voltage – Voltage (V) is the electric potential difference between two points in a circuit.
Energy Storage in Capacitors – The energy stored in a capacitor is directly related to both its capacitance and the square of the voltage across it.
