What should be the voltage across the 3H inductor in the below given electrical circuit if the 5V voltage source has been fed from the input terminal a-b?

Can you help me solve this and explain clearly I saw some answers on chegg but I don’t understand it .

Light-emitting diodes (LEDs) are diodes made with III-V compound semiconductor materials such as aluminum gallium arsenide (AlGaAs), aluminum indium gallium phosphide (AllnGaP) or indium gallium nitride (InGaN), instead of silicon. The LEDs emit light when the device is operated under forward bias. LEDs of different colors have different turn-on voltages VD(on). For example: Color VD(on) Red ~ 1.6 V Yellow ~ 1.7 V (a) Model these five LEDs with a simplified piecewise linear model. (b) A rule of thumb is that it takes about 1 mA of current to "light" an LED while~ 10 mA is needed for it to appear bright. Use the piecewise linear model for the LEDs, for the over-voltage indicator circuit to the right, find the values of Vin which will cause D₁ or D₂ to light (i.e. when ID1 or ID2 exceeds 1 mA).

C'uk Converter Design A C'uk converter has an input of 12 V and is to have an output of - 24 V supplying a 60 W load. Select the duty ratio, the switching frequency, the inductor sizes such that the change in inductor currents is no more than 12 percent of the average inductor current, the output ripple voltage is no more than 1.5 percent, and the ripple voltage across C1 is no more than 3 percent.

Which of the following is correct for a diode ○ A diode conducts in a forward bias A diode conducts in a reverse bias ○ A diode can never conduct as it is an insulator all the time. OA diode is a bi-directional device.
