A 12.0 V battery is hooked up with three resistors (R1, R2, R3) in parallel with resistances of 2.0 Ω, 5.0 Ω, and 10.0 Ω, respectively.
b.) Calculate the total resistance for a parallel circuit.
c.) Calculate the current passing through each resistor in the circuit.
b.) Total resistance for a parallel circuit = 1/(1/R1 + 1/R2 + 1/R3) = 1/(1/2.0 + 1/5.0 + 1/10.0) = 1.67 Ω
c.) Current passing through each resistor = 12.0 V/1.67 Ω = 7.19 A
Current through R1 = 7.19 A
Current through R2 = 7.19 A
Current through R3 = 7.19 A
