An Ohmic Resistor of electrical resistance of 1500 OHM is passed through an electrical current of 1 mA. Determine the potential difference applied to the terminals of this Resistor!

Question

a) 1.5 V

b) 2.5 V

c) 5 V

d) 7.5 V

e) 0.25 V

Answer 1

An Ohmic Resistor, as the name implies, follows the convention of Ohm's Law:

V = I * R

Where V is the potential difference (a.k.a. voltage) between the resistor's terminals.

Where I is the current ran through the resistor's terminals.

Where R is the electrical resistance of the resistor.

V = (1 * 10^-3 A) * (1.5 * 10³ Ω) = 1.5 Ω * A = 1.5 V

Thus, the correct answer is a).
