answer:
Total current = I = I1 + I2 + I3
from ohms law I = V/R,
I1 = V/R1
I2 = V/R2
I3 = V/R3
V/R = V/R1 + V/R2 + V/R3
1/R = 1/R1 + 1/R2 + 1/R3
Explain how to find the resistance of a combination of three resistors of resistance R1, R2, and R3 connected in parallel using a labelled circuit diagram.
