For the circuit shown, what is the rate of change of the current in the inductor when the current in the battery is 0.30 A?

What is the relationship between a sinusoidal current and a sinusoidal voltage in an inductor?

A) What is the maximum current through the inductor? B) What is the first time at which the current is maximum?

A 12.0 V battery is connected into a series circuit containing a 20.0 resistor and a 1.50 H inductor. (a) In what time interval (in s) will the current reach 50.0% of its final value? S (b) In what time interval (in s) will the current reach 90.0% of its final value? S What If? After a very long time, using a switch like that shown in the figure below, the battery is removed and the inductor is connected directly across the resistor. R Są ob ก ε ele (c) In what time interval (in s) will the current decrease to 50.0% of its initial value? S (d) In what time interval (in s) will the current decrease to 10.0% of its initial value? S
