Question: What is the total current in a circuit with a 24V source and two resistors in series, 8Ω and 4Ω?

Options:

Correct Answer: 3 A

Solution:

Total resistance R = 8Ω + 4Ω = 12Ω. Using Ohm\'s Law, I = V / R = 24V / 12Ω = 2 A.

What is the total current in a circuit with a 24V source and two resistors in series, 8Ω and 4Ω?

Step 1: Identify the voltage of the source, which is 24V.
Step 2: Identify the resistors in the circuit, which are 8Ω and 4Ω.
Step 3: Calculate the total resistance by adding the two resistors together: 8Ω + 4Ω = 12Ω.
Step 4: Use Ohm's Law to find the current. Ohm's Law states that current (I) equals voltage (V) divided by resistance (R).
Step 5: Substitute the values into the formula: I = 24V / 12Ω.
Step 6: Calculate the current: 24V divided by 12Ω equals 2 A.
