If a 9V battery is connected to a 3Ω resistor, what is the current flowing through it? (2021)
Step 1: Identify the voltage (V) from the battery, which is 9 volts.
Step 2: Identify the resistance (R) of the resistor, which is 3 ohms.
Step 3: Use Ohm's law formula, which is I = V / R, where I is the current.
Step 4: Substitute the values into the formula: I = 9V / 3Ω.
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).
Ohm's Law – Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor.
