Figure 27-41 shows a battery connected across a uniform resistor R_0. A sliding contact can move across the resistor from x=0 at the left x= 10 cm at the right. Moving the contact changes how much resistance is to the left of the contact and how much is to the right. Find the rate at which energy is dissipated resistor R as a function of x. Plot the function for epsi_(0)=50V, R=2000 Omega and R_(0)=100 Omega |
