When the voltage source is turned off in a simple circuit consists of a resistor and an inductor, the rate of decrease of the current is proportional to the current. The current is 40 amperes at the moment that the switch is off and dies down to 15 amperes after 0.01 sec. Determine the current in 0.02 sec. 3.375 amperes 4.25 amperes 5.625 amperes 6.025 amperes

In the circuit below, switch S is initially disconnected from points A and B. The switch is then connected to A. What is the current and voltage in the resistors and inductor: a) as soon as the switch is turned on b) long after the key is turned on. The switch is then suddenly disconnected from A and connected to B: c) What is the current in the resistors at that moment? d) What is the voltage in the inductor? e) After that moment, what is the total energy dissipated by the resistors?

What is the current in the inductor ILO in continuity mode before opening the switch. R₁ Select one: O a. I = O b. I = E R₁ R₂ R₁+R₂ = E R₂ O c. I=0 O d. I E R₁ E k R₂ ILO L

Draw the charging and discharging waveform if the switch changed position precisely when the capacitor reached 5 time constants when charging and discharging.
