Question

Voltage V(volts),current I(amperes)and resistance R(ohms)of an electric circuit have equation V=IR, suppose that R increases at rate 1/2 ohm/sec. Find the rate at which the current decreases when I=2 amperes and V is kept constant at 10 volts.

V = IR
dV/dt = R dI/dt + I dR/dt
now plug in your numbers to find dI/dt
