Question: If a circuit has a Thevenin equivalent of 5V and a load resistance of 10Ω, what is the load current?

Options:

  1. 0.5A
  2. 1A
  3. 2A
  4. 5A

Correct Answer: 1A

Solution: 

Using Ohm\'s law, I = V / R = 5V / 10Ω = 0.5A.

Questions & Step-by-Step Solutions

If a circuit has a Thevenin equivalent of 5V and a load resistance of 10Ω, what is the load current?
  • Step 1: Identify the Thevenin equivalent voltage, which is given as 5V.
  • Step 2: Identify the load resistance, which is given as 10Ω.
  • Step 3: Use Ohm's law to find the load current. Ohm's law states that current (I) equals voltage (V) divided by resistance (R).
  • Step 4: Substitute the values into the formula: I = V / R = 5V / 10Ω.
  • Step 5: Calculate the result: 5V divided by 10Ω equals 0.5A.
  • Step 6: Conclude that the load current is 0.5A.
  • Thevenin's Theorem – Thevenin's Theorem simplifies a complex circuit into a single voltage source and series resistance.
  • Ohm's Law – Ohm's Law relates voltage, current, and resistance in an electrical circuit, expressed as I = V / R.
