Questions & Step-by-Step Solutions

What is the total power dissipated in a circuit with a 24V source and a load of 6Ω?
  • Step 1: Identify the voltage (V) in the circuit. In this case, V = 24 volts.
  • Step 2: Identify the resistance (R) of the load. Here, R = 6 ohms.
  • Step 3: Use the power formula P = V^2 / R to calculate the power.
  • Step 4: Substitute the values into the formula: P = 24^2 / 6.
  • Step 5: Calculate 24^2, which equals 576.
  • Step 6: Divide 576 by 6 to find the power: 576 / 6 = 96.
  • Step 7: Conclude that the total power dissipated in the circuit is 96 watts.
