Questions & Step-by-Step Solutions

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