In the above circuit, the switch is open for a long time. i)The switch closes for 50 us. What is the current through the inductor? Also, what is the voltage at the output with respect to ground just before the switch open?
ii) The switch closes. What is the maximum current the inductor will see?

How do we measure or think of speed in the united states?

In an experiment, how can i change human errors? be specific.

Atoaster oven has a resistive heating element. the average rate at which it dissipates energy as thermal energy is 1.00 \(\rm kw\). in the united states, emf amplitude in household circuits is \(\mathcal e_{\max}\) = 170 \({\rm \; v}\) and the \(\rm ac\) oscillation rate is 60 \(\rm hz\). part a what is the root-mean-square current through the heating element?
