Questions & Step-by-Step Solutions

In a circuit with a 12V battery and a 3Ω load resistor, what is the current flowing through the load?
  • Step 1: Identify the voltage of the battery, which is 12V.
  • Step 2: Identify the resistance of the load resistor, which is 3Ω.
  • Step 3: Recall Ohm's law, which states that current (I) equals voltage (V) divided by resistance (R).
  • Step 4: Plug the values into the formula: I = V / R.
  • Step 5: Substitute the known values: I = 12V / 3Ω.
  • Step 6: Calculate the result: 12 divided by 3 equals 4.
  • Step 7: Conclude that the current flowing through the load is 4A.
