Question: What is the total current flowing in a circuit with a 9V battery and a total resistance of 3 ohms? (2020)

Options:

Correct Answer: 2 A

Exam Year: 2020

Solution:

Using Ohm\'s law, I = V/R = 9V / 3Ω = 3 A.

What is the total current flowing in a circuit with a 9V battery and a total resistance of 3 ohms? (2020)

Step 1: Identify the voltage of the battery. In this case, it is 9 volts (V).
Step 2: Identify the total resistance in the circuit. Here, it is 3 ohms (Ω).
Step 3: Use Ohm's law to find the current. Ohm's law states that current (I) equals voltage (V) divided by resistance (R).
Step 4: Plug in the values into the formula: I = V / R = 9V / 3Ω.
Step 5: Calculate the result: 9 divided by 3 equals 3.
Step 6: Conclude that the total current flowing in the circuit is 3 amperes (A).
