Question

when a 12V battery is connected across an unknown resistor,there is a current of 2.5 mA in the circuit . find the value of the resistance of the resistor​

Answer 1

Answer:

R = 4800 Ω is the correct answer.

Explanation:

Let the value of "Unknown resistor" be 'R'.

⇒ V = I × R

⇒ 12 Volts = (2.5 × 10⁻³ Ampere) × R

⇒ ∴ R = 12 ÷ (2.5 × 10⁻³)

⇒ ∴ R = 4800 Ω              ←ANSWER

Answer 2

Answer:

R=V/I

R=12/2.5

=4.8 ohm
