Questions & Step-by-Step Solutions

In a circuit with a 15V source and a 5Ω resistor, what is the current flowing through the resistor?
  • Step 1: Identify the voltage (V) in the circuit. In this case, V = 15 volts.
  • Step 2: Identify the resistance (R) in the circuit. Here, R = 5 ohms.
  • Step 3: Use Ohm's law formula, which is I = V / R, to find the current (I).
  • Step 4: Substitute the values into the formula: I = 15V / 5Ω.
  • Step 5: Calculate the result: 15 divided by 5 equals 3.
  • Step 6: Conclude that the current flowing through the resistor is 3 amperes (A).
