Questions & Step-by-Step Solutions

What is the total current flowing through a circuit with a 10V battery and two 5Ω resistors in series?
  • Step 1: Identify the voltage of the battery, which is 10V.
  • Step 2: Identify the resistors in the circuit. There are two resistors, each with a resistance of 5Ω.
  • Step 3: Calculate the total resistance in the circuit. Since the resistors are in series, add their resistances together: 5Ω + 5Ω = 10Ω.
  • Step 4: Use Ohm's law to find the current. Ohm's law states that current (I) equals voltage (V) divided by resistance (R): I = V/R.
  • Step 5: Substitute the values into the formula: I = 10V / 10Ω.
  • Step 6: Calculate the current: I = 1A.
