What is the resistance of a resistor if at a voltage of 10 V the current in it is 10 mA?

Data: U (voltage across the specified resistor) = 10 V; I (current in the resistor) = 10 mA = 0.01 A.

To determine the resistance of the specified resistor, apply Ohm’s law: R = U / I = 10 / 0.01 = 103 Ohm = 1 kOhm.

Answer: The resistance of the resistor is 1 kΩ.
