Question

What is the potential difference between two locations if their individual potentials are 4.5 V and 2.3 V?

  1. 7.8 V
  2. 7.5 V
  3. -2.2 V
  4. 2.2 V

hintHint:

Vab= Va-Vb

The correct answer is: 2.2 V


    • Potential difference between two points is written as Vab= Va-Vb
    • Given, Va= 4.5V and Vb=2.3V
    • Therefore, Vab= 4.5-2.3 = 2.2V. 
    • So, the correct option is d.
