Question: If a circuit has a Thevenin equivalent of 15V and a load resistance of 5Ω, what is the load current?

Options:

  1. 3A
  2. 2A
  3. 1A
  4. 0.5A

Correct Answer: 2A

Solution: 

Using Ohm\'s law: I = V/R = 15V / 5Ω = 3A.

Questions & Step-by-Step Solutions

If a circuit has a Thevenin equivalent of 15V and a load resistance of 5Ω, what is the load current?
  • Step 1: Identify the Thevenin equivalent voltage, which is given as 15V.
  • Step 2: Identify the load resistance, which is given as 5Ω.
  • Step 3: Use Ohm's law formula, which is I = V / R, where I is the current, V is the voltage, and R is the resistance.
  • Step 4: Substitute the values into the formula: I = 15V / 5Ω.
  • Step 5: Calculate the current: I = 3A.
  • Thevenin's Theorem – Thevenin's Theorem simplifies a complex circuit to a single voltage source and a series resistance.
  • Ohm's Law – Ohm's Law relates voltage (V), current (I), and resistance (R) in a circuit, expressed as I = V/R.
