Question

When a 15v battery is connected across an unknown resistor , there is a current of 1.5 mA in the circuit . find the value of resistence of the resistor

Answer 1

Answer:

Value of resistance of Resistor = 1000 Ω

Explanation:

We Have :-

15 V battery

15 mA current in the circuit

To Find :-

Resistance

Formula Used :-

V = IR ( Ohm's Law )

Solution :-

Let the resistance be R

Current = 15 mA = 0.015 A

15 = 0.015 * R

R = 15 / 0.015

R = 15000 / 15

R = 1000 Ω

Value of resistance of Resistor = 1000 Ω
