Questions & Step-by-Step Solutions

What is the total current flowing in a circuit with a 9V battery and a total resistance of 3 ohms? (2020)
  • Step 1: Identify the voltage of the battery. In this case, it is 9 volts (V).
  • Step 2: Identify the total resistance in the circuit. Here, it is 3 ohms (Ω).
  • Step 3: Use Ohm's law to find the current. Ohm's law states that current (I) equals voltage (V) divided by resistance (R).
  • Step 4: Plug in the values into the formula: I = V / R = 9V / 3Ω.
  • Step 5: Calculate the result: 9 divided by 3 equals 3.
  • Step 6: Conclude that the total current flowing in the circuit is 3 amperes (A).
