Questions & Step-by-Step Solutions

What is the total power consumed in a circuit with a 24V source and a total resistance of 6Ω?
  • Step 1: Identify the voltage (V) in the circuit, which is given as 24 volts.
  • Step 2: Identify the total resistance (R) in the circuit, which is given as 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 = (24V)^2 / 6Ω.
  • Step 5: Calculate (24V)^2, which equals 576.
  • Step 6: Divide 576 by 6Ω to find the power: 576 / 6 = 96W.
  • Step 7: Conclude that the total power consumed in the circuit is 96 watts.
