How much energy is expended in moving a 20 coulomb charge through a potential difference of 0.5 volts?
Question
How much energy is expended in moving a 20 coulomb charge through a potential difference of 0.5 volts?
Solution
The energy expended in moving a charge through a potential difference (voltage) can be calculated using the formula:
E = Q * V
Where: E is the energy in joules (J) Q is the charge in coulombs (C) V is the potential difference in volts (V)
Here are the steps to calculate the energy:
-
Identify the charge (Q). In this case, the charge is 20 coulombs.
-
Identify the potential difference (V). In this case, the potential difference is 0.5 volts.
-
Multiply the charge (Q) by the potential difference (V) to calculate the energy (E) in joules.
E = Q * V E = 20 C * 0.5 V E = 10 J
Therefore, the energy expended in moving a 20 coulomb charge through a potential difference of 0.5 volts is 10 joules.
