- Ohm's law: It states that the electric potential difference is directly proportional to the current flowing through a conductor at constant temperature and other physical quantities.
So V = I R
Where V is potential difference, I is electric current and R is resistance
CALCULATION:
Given that:
Resistnace (R) = 2.5 kΩ = 2500 Ω
Current (I) = 2 mA = 0.002 A
V = IR
V = 2500 × 0.002
V = 5.0
Potential Difference = 5V.
