Answer 1

Answer:

8 joules

Explanation:

Answer 2

Given : 4 volts E.M.F. is applied across a 1 farad capacitor.

To find : The energy stored in the capacitor.

Solution :

We can simply solve this numerical problem by using the following process. (our goal is to calculate the energy stored in the capacitor)

Here, we will be using the following formula.

U = ½ × C × V²

Where,

• U = Energy stored in the capacitor
• C = Capacitance
• V = Voltage (or, E.M.F.)

By, putting the available data in the above mentioned formula, we get -

Energy stored in the capacitor = ½ × 1 × (4)² = 8 joules

(This will be considered as the final result.)

Hence, it will store 8 joules of energy.
