Understanding Resistor Combinations
When resistors are connected in parallel, the total current flowing through the circuit is the sum of the currents through each resistor. The voltage across each resistor in parallel is the same and equal to the voltage of the battery.
Given Values
- Resistors: R1 = 3Ω, R2 = 4Ω, R3 = 5Ω
- Voltage (V) = 12V
Calculating Current through Each Resistor
Using Ohm's Law (I = V/R), the current through each resistor can be calculated as follows:
- Current through R1 (3Ω):
- I1 = V/R1 = 12V / 3Ω = 4A
- Current through R2 (4Ω):
- I2 = V/R2 = 12V / 4Ω = 3A
- Current through R3 (5Ω):
- I3 = V/R3 = 12V / 5Ω = 2.4A
Summary of Currents
The current through each resistor is:
- I1 = 4A through the 3Ω resistor
- I2 = 3A through the 4Ω resistor
- I3 = 2.4A through the 5Ω resistor
Final Answer
Thus, the correct answer for the current through each resistor is option 'A':
- 4A (3Ω), 3A (4Ω), 2.4A (5Ω)
