Question

Find the energy lost by 10 C going from A to B if the potential difference between A and B is 12 V.

a) 1.2 J
b) 22 J
c) 0.83 J
d) 120 J

Answer 1

The energy lost by 10 C of charge moving through a potential difference of 12 V is calculated using the formula E = qV, resulting in an energy loss of 120 J.

Step-by-step explanation:

To find the energy lost by 10 C of charge moving through a potential difference of 12 V from point A to point B, we can use the formula for electrical potential energy, which is:

Energy (E) = Charge (q) × Potential Difference (V)

By inserting the given values into the formula, we get:

E = 10 C × 12 V = 120 J

Therefore, the energy lost by 10 C of charge moving from A to B is 120 joules.
