Question
10. A large research solenoid has a self-inductance of 20.0 H.
What induced emf (in V) opposes shutting it off when 125 A of current through it is switched off in 84.0 ms?
V
How much energy (in J) is stored in the inductor at full current?
J
At what rate in watts must energy be dissipated to switch the current off in 84.0 ms?
W
In view of the answer to the last part, is it surprising that shutting it down this quickly is difficult?
