Question

When a 40V battery is connected across an unknown resistor there is a current of 100 mA in the circuit. The value of the resistance of the resistor is

Answer 1

Answer:

R = 400 Ohm's

Explanation:

Voltage of the battery, V = 40 V

current in the unknown register I = 100mA

Let R is the resistance of the resistor. it can be calculated using Ohm's law it gives the relationship between the voltage resistance and current.

R = V/I

R = 40V/ 10-¹A

R = 400 Ohm's

So, the value of the resistance of the resistor is 400 Ohm's. Hence, this is the required solution.
