Question: In a circuit with a Norton equivalent, if the short-circuit current (Isc) is 3A and the Norton resistance (Rn) is 5Ω, what is the Norton equivalent voltage (Vn)?

Options:

  1. 15V
  2. 10V
  3. 5V
  4. 3V

Correct Answer: 15V

Solution:

Norton voltage can be calculated using Ohm\'s law: Vn = Isc * Rn = 3A * 5Ω = 15V.

Questions & Step-by-Step Solutions

In a circuit with a Norton equivalent, if the short-circuit current (Isc) is 3A and the Norton resistance (Rn) is 5Ω, what is the Norton equivalent voltage (Vn)?
  • Step 1: Identify the short-circuit current (Isc) given in the problem, which is 3A.
  • Step 2: Identify the Norton resistance (Rn) given in the problem, which is 5Ω.
  • Step 3: Use Ohm's law to find the Norton equivalent voltage (Vn). The formula is Vn = Isc * Rn.
  • Step 4: Substitute the values into the formula: Vn = 3A * 5Ω.
  • Step 5: Calculate the result: Vn = 15V.
  • Norton Equivalent Circuit – A representation of a complex circuit as a current source in parallel with a resistor.
  • Ohm's Law – A fundamental principle stating that voltage (V) is the product of current (I) and resistance (R), expressed as V = I * R.
