9.2 An AC generator is operating at a maximum emf of 340 V. It is connected
across a toaster and a kettle, as shown in the diagram below.
generator
800 W
2 000 W
The toaster is rated at 800 W, whlle the kettle is rated at 2 000 W. Both are
working under optimal conditions.
Calculate the:
9.2.1
mms current passing through the toaster
(3)
9.2.2
Total mms current delivered by the generator
(4)
1113

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,?
