Questions & Step-by-Step Solutions

What is the Thevenin equivalent voltage if a circuit has a 12V source and a 4Ω resistor in series with a 2Ω load?
  • Step 1: Identify the components in the circuit. We have a 12V voltage source, a 4Ω resistor, and a 2Ω load resistor.
  • Step 2: Recognize that the 4Ω resistor and the 2Ω load resistor are in series.
  • Step 3: Calculate the total resistance in the series circuit. Total resistance = 4Ω + 2Ω = 6Ω.
  • Step 4: Use the voltage division rule to find the voltage across the load resistor (2Ω). The formula is V_load = V_source * (R_load / (R_series)).
  • Step 5: Substitute the values into the formula: V_load = 12V * (2Ω / 6Ω).
  • Step 6: Simplify the fraction: 2Ω / 6Ω = 1/3.
  • Step 7: Calculate V_load: V_load = 12V * (1/3) = 4V.
  • Step 8: Conclude that the Thevenin equivalent voltage is 4V.
