A real battery (modeled as an ideal emf device in series with an internal resistor) is connected to a lightbulb. As the battery ages, its internal resistance increases while the internal ideal emf device remains unchanged. As the battery ages, what happens to a. the terminal potential of the real battery.
b. the current in the circuit.
c. the light emitted.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
