If two resistors with resistances R, and Ry are wired in parallel, then their combined resistance R is given by the complex fraction R= R, R₂
Evaluate this formula when R1 = 70 ohms and R2 = 125 ohms.

The equivalent resistance of two resistances connected in parallel is given by 1/R = 1/R1 + 1/R2

R = (R1*R2)/(R1 + R2)

(dR)/(dt) = ((R1*(dR2)/dt + R2*(dR1)/dt)(R1 + R2) - (R1*R2*((dR1)/dt + (dR2)/dt)))/(R1 + R2)^2

R1 is increasing at a rate of 0.3 ohms/second and R2 is increasing and finish i am busy right now am sorry to finish this question here ur formula
