In a circuit with two resistors in parallel, if one resistor is 4Ω and the other is 12Ω, what is the total current flowing through the circuit when connected to a 24V battery?
Correct Answer: 8A
Step 1: Identify the resistors in the circuit. We have one resistor of 4Ω and another of 12Ω.
Step 2: Use the formula for equivalent resistance in parallel: 1/R_eq = 1/R1 + 1/R2.
Step 3: Substitute the values into the formula: 1/R_eq = 1/4 + 1/12.
Step 4: Find a common denominator to add the fractions. The common denominator for 4 and 12 is 12.
Step 5: Rewrite the fractions: 1/4 = 3/12 and 1/12 = 1/12.
