Questions & Step-by-Step Solutions

In a circuit with a 9 V battery and a 3 ohm resistor, what is the current flowing through the circuit?
  • Step 1: Identify the voltage of the battery, which is 9 volts.
  • Step 2: Identify the resistance of the resistor, which is 3 ohms.
  • Step 3: Use Ohm's law formula, which is I = V / R, where I is the current, V is the voltage, and R is the resistance.
  • Step 4: Plug in the values into the formula: I = 9 V / 3 ohms.
  • Step 5: Calculate the current: 9 divided by 3 equals 3.
  • Step 6: Conclude that the current flowing through the circuit is 3 amperes (A).
