Questions & Step-by-Step Solutions

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