Questions & Step-by-Step Solutions

If a circuit has a Norton equivalent current of 3A and a Norton equivalent resistance of 4Ω, what is the equivalent voltage?
Correct Answer: 12V
  • Step 1: Identify the Norton equivalent current (I) which is given as 3A.
  • Step 2: Identify the Norton equivalent resistance (R) which is given as 4Ω.
  • Step 3: Use Ohm's Law formula, which states that Voltage (V) = Current (I) * Resistance (R).
  • Step 4: Substitute the values into the formula: V = 3A * 4Ω.
  • Step 5: Calculate the result: V = 12V.
  • Norton Theorem – Norton Theorem states that any linear electrical network can be replaced by an equivalent current source in parallel with a resistor.
  • Ohm's Law – Ohm's Law relates voltage (V), current (I), and resistance (R) in a circuit, expressed as V = I * R.
