What is the total current in a circuit with a 12V battery and two 6Ω resistors in series? (2021)
  • Step 1: Identify the voltage of the battery, which is 12V.
  • Step 2: Identify the resistance of each resistor, which is 6Ω.
  • Step 3: Since the resistors are in series, add their resistances together: 6Ω + 6Ω = 12Ω.
  • Step 4: Use Ohm's Law to find the current. Ohm's Law states that Current (I) = Voltage (V) / Resistance (R).
  • Step 5: Substitute the values into the formula: I = 12V / 12Ω.
  • Step 6: Calculate the current: I = 1A.
