An electric current of 4.0A flows through a 12Omega resistor. What is the rate at which heat energy is produced in the resistor?

If two resistors of R_(1) and R_(2) ohms are connected in parallel in an electric circuit to make an R ohm resistor, the value of R can be found from the equation, (1)/(R)=(1)/(R_(1))+(1)/(R_(2)) If R_(1) is decreasing at the rate of 1 ohm/sec and R_(2) i increasing at the rate of 0.5 ohm/sec, at what rate is R changing when R_(1)=75 ohm and R_(2)=50 ohm ?
