Question

12 battery resistor 2.5ma current flows through the circuit if so what is resistance of resistor

Answer 1

Answer:

48000 ohm

Explanation:

In the question

Voltage= 12 V

Current= 2.5 mA = 2.5 x 10⁻³

Acc. to Ohm's law, V= IR

→  12= 2.5 x 10⁻³ x R

→ 12 = 25 x 10⁻⁴ x R

→ 12 x 10⁴ = 25 x R

→ 12 x 4 x 10³ = R

→48000 ohm = Resistance
