Voltage Physics Example 1

Follow the full solution, then compare it with the other examples linked below.

Example 1

easy
A battery does 24 J24 \text{ J} of work to move 6 C6 \text{ C} of charge. What is the voltage of the battery?

Solution

  1. 1
    Voltage is work done per unit charge: V=WQV = \frac{W}{Q}.
  2. 2
    Substitute the values: V=246V = \frac{24}{6}.
  3. 3
    V=4 VV = 4 \text{ V}

Answer

V=4 VV = 4 \text{ V}
Voltage (potential difference) is the energy transferred per coulomb of charge. A higher voltage means more energy per charge, driving more current through a circuit.

About Voltage
