Question: If a circuit has a Norton equivalent current of 2A and a Norton resistance of 3Ω, what is the Thevenin equivalent resistance?

Options:

Correct Answer: 3Ω

Solution:

Thevenin resistance is equal to Norton resistance: Rth = Rn = 3Ω.

If a circuit has a Norton equivalent current of 2A and a Norton resistance of 3Ω, what is the Thevenin equivalent resistance?

If a circuit has a Norton equivalent current of 2A and a Norton resistance of 3Ω, what is the Thevenin equivalent resistance?

Step 1: Understand that Norton and Thevenin equivalents are two ways to represent the same circuit.
Step 2: Know that the Norton equivalent consists of a current source (In) and a parallel resistance (Rn).
Step 3: Recognize that the Thevenin equivalent consists of a voltage source (Vth) and a series resistance (Rth).
Step 4: Remember the relationship between Norton resistance (Rn) and Thevenin resistance (Rth): they are equal.
Step 5: Since the Norton resistance is given as 3Ω, we can conclude that the Thevenin resistance is also 3Ω.
