Questions & Step-by-Step Solutions

What is the total power consumed in a circuit with a 12V battery supplying a current of 2A?
  • Step 1: Identify the voltage (V) from the battery, which is 12 volts.
  • Step 2: Identify the current (I) flowing in the circuit, which is 2 amperes.
  • Step 3: Use the formula for power (P), which is P = V * I.
  • Step 4: Substitute the values into the formula: P = 12V * 2A.
  • Step 5: Calculate the result: 12 * 2 = 24.
  • Step 6: State the total power consumed, which is 24 watts.
