Questions & Step-by-Step Solutions

In an AC circuit, if the voltage is 120V and the current is 10A with a power factor of 0.8, what is the real power consumed? (2021)
  • Step 1: Identify the voltage (V) in the circuit, which is given as 120V.
  • Step 2: Identify the current (I) in the circuit, which is given as 10A.
  • Step 3: Identify the power factor, which is given as 0.8.
  • Step 4: Use the formula for real power (P), which is P = V * I * power factor.
  • Step 5: Substitute the values into the formula: P = 120V * 10A * 0.8.
  • Step 6: Calculate the result: 120 * 10 = 1200, then 1200 * 0.8 = 960.
  • Step 7: Conclude that the real power consumed is 960W.
