Calculation:
To calculate the energy required to move a certain amount of charge through a given potential difference, we can use the formula:
Energy (E) = Charge (Q) × Potential Difference (V)
Given:
Charge (Q) = 120 C
Potential Difference (V) = 3 V
Let's substitute these values into the formula:
E = 120 C × 3 V
E = 360 J
Therefore, the energy required to move 120 coulombs through a potential difference of 3 volts is 360 joules.
Explanation:
When a charge is moved through a potential difference, work is done and energy is required. The amount of energy required is directly proportional to both the charge being moved and the potential difference across which it is moved. The formula E = Q × V represents this relationship, where E is the energy in joules, Q is the charge in coulombs, and V is the potential difference in volts.
In this case, the charge Q is given as 120 coulombs and the potential difference V is given as 3 volts. By substituting these values into the formula, we can calculate the energy required as:
E = 120 C × 3 V
E = 360 J
Therefore, the energy required to move 120 coulombs through a potential difference of 3 volts is 360 joules.
