Question

12 volt battery is concerned across an unknown resister , there is a 2.5mA in the circuit. Find the value of the resistance of the resistor​

Answer 1

Answer:

We have potential difference (V) = 12V

Electric current (I)=2.5 mA= 2.5×10-3

According to Ohm’s Law (V) = IR

Or  R = V/I

R = 12/ 2.5 × 10⁻³

∴ R = 4.8 × 10⁻³ Ω
