Question: In a circuit with a 24V battery and two 12Ω resistors in series, what is the current flowing through the circuit?
Options:
1A
2A
3A
4A
Correct Answer: 2A
Solution:
Total resistance R_total = 12Ω + 12Ω = 24Ω. Current I = V/R_total = 24V / 24Ω = 1A.

Questions & Step-by-Step Solutions
In a circuit with a 24V battery and two 12Ω resistors in series, what is the current flowing through the circuit?
Step 1: Identify the voltage of the battery, which is 24V.
Step 2: Identify the resistance of each resistor, which is 12Ω.
Step 3: Since the resistors are in series, add their resistances together: 12Ω + 12Ω = 24Ω.
Step 4: Use Ohm's Law to find the current. Ohm's Law states that Current (I) = Voltage (V) / Resistance (R).
Step 5: Substitute the values into the formula: I = 24V / 24Ω.
Step 6: Calculate the current: I = 1A.
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.
Series Circuits – In a series circuit, the total resistance is the sum of the individual resistances, and the same current flows through all components.
