Questions & Step-by-Step Solutions

In a series circuit with a 12V battery and two resistors (4Ω and 6Ω), what is the total current flowing through the circuit?
  • Step 1: Identify the voltage of the battery, which is 12V.
  • Step 2: Identify the resistors in the circuit, which are 4Ω and 6Ω.
  • Step 3: Calculate the total resistance in the circuit by adding the resistances together: 4Ω + 6Ω = 10Ω.
  • 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 / 10Ω.
  • Step 6: Calculate the current: 12V divided by 10Ω equals 1.2 A.
