Aresistor, an inductor, and a switch are all connected in series to an ideal battery of constant terminal voltage. suppose at first the switch is open, and then, at some initial time t = 0, it is closed. which of the following statements are true?
a. the steady-state value of the current depends on the resistance of the resistor.
b. at the instant the switch is closed, the current reaches its steady-state value.
c. the steady-state value of the current depends on the inductance of the inductor.
d. at the instant the switch is closed, the current begins to increase at a rate that depends upon the value of the inductance of the inductor.

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?
