Question

If two resistors with resistances R1 and R2 are connected
in parallel, as in the figure, then the total resistance R , measured in ohms (Ω ), is given by

 

1/R= 1/R1 +1/R2
If R1 and  r2 are increasing at rates of  0.3 Ω/s and 0.2 Ω/s ,
respectively, how fast is R changing when R1 = 80Ω/s and R2 =100Ω
?
