Determine the equivalent resistance of two resistances linked in parallel with the help of a circuit diagram. 

Answer:

The above circuit shows resistances R1 and R2 connected in series with a battery of V volts

Total current = I = I1 + I2

apply ohms law,

I=V/R

I1 = V/R1

I2 = V/R2

V/R = V/R1 + V/R2

1/R = 1/R1 + 1/R2
