Yes. For a condition called 'series resonance', if the resistance of the circuit is low compared with the inductive reactance and capacitive reactance, then the voltage drop across the capacitor can be VERY much higher than the supply voltage.

Absolutely. At resonance, if the circuit has a very low resistance in comparison to its inductive and capacitive reactances, then the voltage across the reactive component of the coil can be many times larger than the supply voltage. Good news for electronics engineers; bad news for power-systems engineers (check out 'ferroresonance').

Yes. Both a capacitor and an inductor will exhibit this characteristic when driven with an AC source, because they are both stored energy devices.

Is it possible to have a voltage drop across the energy storage element greater than the supply in series RLC circuit?

If, by 'storage element', you are are referring to the inductive and capacitive components (?), then the answer is yes. The voltage drop across these components is given by:VL = I XLVC = I XCIn fact, at resonance, if the resistance is low, then VLand VC can be very much higher than the supply voltage.

Which voltage is greater in thyristor whether forward breakover or reverse breakdown voltage?

One voltage is greater in thyristor whether forward breakover or reverse breakdown voltage. The greater of the two voltages in thyristor is forward breakover voltage.


True or False The voltage rating of a fuse can be greater than the circuit voltage?

True. The voltage rating of a fuse must be greater than the circuit voltage.


Which voltage is greater in thyristor whether forward break over or reverse breakdown voltage?

It is stated that one of the voltage is greater in thyristor whether it be forward breakover or reverse breakdown voltage. It is also stated that the greater of the 2 voltages in thyristor is the forward breakover voltage.

What is unilateral element?

When an element polarity of voltage or current source changes, the magnitude of the corresponding current or voltage changes is called unilateral element. Eg: Diode Even Diode connected back to back in parallel act as a Bilateral.


Why is it possible to measure an electric potential across the terminals of a dry cell?

Batteries are a voltage storage device that hold a voltage potential until used. By using a volt meter you can find the stored voltage by placing the leads of the meter across the battery's positive and negative terminals.
