Questions & Step-by-Step Solutions
A 9V battery is connected to a circuit with a total resistance of 3Ω. What is the total current flowing in the circuit? (2023)
Step 1: Identify the voltage of the battery, which is 9V.
Step 2: Identify the total resistance in the circuit, which is 3Ω.
Step 3: Recall Ohm's law, which states that current (I) equals voltage (V) divided by resistance (R).
Step 4: Plug the values into the formula: I = V / R.
Step 5: Substitute the values: I = 9V / 3Ω.
Step 6: Calculate the result: 9 divided by 3 equals 3.
Step 7: Conclude that the total current flowing in the circuit is 3A.
Ohm's Law – Ohm's Law states that the current (I) flowing 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.
