4. [T] If two electrical resistors are connected in parallel, the total resistance (measured in ohms, denoted by the Greek capital letter omega, 2)

4. [T] If two electrical resistors are connected in parallel, the total resistance (measured in ohms, denoted by the Greek capital letter omega, 2) is given by the equation 1. R .If R, is increasing at a rate of 0.5 2/min + %D R1 R2 and R2 decreases at a rate of 1.12/min, at what rate does the total resistance change when R, 202 and %3D R2 = 502/min?
