1. bec the capacitor not allow the current to pass through it after it has charged & it charged in no time ex:(10^-4 second).
2. because it is necessary to avoid wrong polarity by shorting the terminals of the capacitor and tripping the fuse.

How to connect 3 phase power factor correction capacitor?
how to connect power capacitor with 3 phase motor
What diode is used as voltage controlled capacitor?
It is called a varactor or a varicap diode. Its capacitance varies nonlinearly with the reverse voltage applied to its terminals.
How capacitor is connected in a table fan?
The Capacitor with running winding is connected in parallel with main winding.
What happen if you connect capacitor and resistor in parallel in low pass filter?
Only frequencies in the pass band range will be allowed through the circuit. Other frequencies will be attenuated based on the RC values picked.
An air-filled parallel-plate capacitor is connected to a battery and allowed to charge up Now a slab of dielectric material is placed between the plates of the capacitor while the capacitor is still?
the charge on the capacitor had increased.
How to construct a battery eliminator?
First you connect a trnsformer to the main supply and then a rectfier .youmay connect a zener diode or a resistor or a capacitor as a filter circuit
What type of diode is used as a variable capacitor?
varactor diode is a correct answer
Can you use a capacitor instead of zener diode in biased clipping circuit?
No. The purpose of the zener diode is to clip (turn on) at a certain voltage. A capacitor will not exhibit this behavior.
What are the different types of semiconductor?
Transistor Diode Resistor Capacitor
Did someone ask the question can you use a transistor as a diode there is a device called a transistor diode connect base to either c or e forgot which to make a zero bias diode?
You can use a transistor as a diode if you connect the base to the collector. Any forward current through the base-emitter junction would cause a corresponding increase in the available current through the collector-emitter junction. Since the base-emitter and collector-emitter junctions are in parallel, this would effectively be a diode, but a true diode would be a better solution if diode functionality is what seek. A: There are actually two diodes, per se, inside a transistor. The base to emitter diode will suffice. By tying the collector to the base it will in effect be two diodes in parallel.

What is the definition of series and parallel resonant circuits?
just like it soundsseries resonant has capacitor & inductor in seriesparallel resonant has capacitor & inductor in parallel
What diode is used as voltage controlled capacitor?
It is called a varactor or a varicap diode. Its capacitance varies nonlinearly with the reverse voltage applied to its terminals.
How do you use a diode to charge your saltwater capacitors with ac voltage?
Simply include the diode in one of the AC supply lines to your capacitor. (not sure what a salt water capacitor is) but, all capacitors only store charge, which is discharged as a DC current.
How capacitor is connected in a table fan?
The Capacitor with running winding is connected in parallel with main winding.
How do you connect diodes in series?
Connect positive to negative, leaving the end positive and negative connections free to power circuits or devices. Connecting batteries in series adds the voltage of the batteries. For instance, connecting three 12v car batteries in series will create a total of 36v, enough for welding.
What does a capacitor in a microwave oven do?
The capacitor in a microwave oven, along with its associated high voltage diode, form what is called a voltage doubler to drive the magnetron.
