Question
A current of 200 Milli ampere flows through 4 k ohm resistance. What is the potential difference across the resistor?
Open in App
Solution
Given'
Current(I) = 200 mA or 200 × 10^-3
Resistance(r) = 4k ohms or 4 × 10^3
Potential difference =?
We know,
Ohm's law:
V = IR
V = 200 × 10^-3 × 4 × 10^3
V = 800 volts
Hence potential difference across the resistor = 800 volts
