A: A TRANSISTOR gain is determined by current flow on the collector by adding a resistor to the emitter this current flow is reduced by adding or bypassing this resistor with a capacitor the net effect is that this emitter resistor will be reduced in value as frequency increases therefore change gain as a function of frequency input

When excessive voltage is applied to a capacitor it will break down What factor of the capacitor has the greatest effect on breakdown voltage?
The dielectric material between the plates.
Why voltage across capacitor goes to zero when wires connected to each terminal of charged capacitor are brought into contact?
The voltage goes to zero because a current path has been created between the positive and negative elements of the capacitor, discharging the stored charge and putting both the anode and cathode of the capactor at the same electrical potential. Thus, no voltage difference between them, which is why the voltmeter reads zero.
Why is voltage rating of a capacitor important to the user?
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.
When a battery is connected with a capacitor the potential difference will?
Charge the capacitor. Potential difference is a scientific term for what is more commonly called voltage. ANSWER: If big enough the battery will see a short initially and then proceed to charge the capacitor at a rate of 63% of the voltage in one time constant defined as RC For engineering purposes after 5 time the time constant the battery will and the capacitor zero potential different. The proper term should be virtual no difference.
What is a capacitor analyzer designed to read?
Capacitor voltage
What is the voltage obtained when a capacitor is placed in a dc circuit?
Eventually, the capacitor will charge to approximately the source voltage level. As this occurs, the current in the circuit will drop to near zero.
Why does the voltage reading drop in measuring the potential difference across the capacitors?
Because the capacitor discharges. so voltage across the capacitor decreases.
What is the difference between capacitor and capacitance?
A capacitor is a device that stores an electrical charge, or if you prefer- resists any change in voltage applied to it. Capacitance is a measure of the size or ability of a capacitor to do that. This is the Farad
Relation between voltage and current if you consider capacitor ckt?
In a capacitor ckt, current will be lead ahead from voltage by an angle 90 degree. Because for a capacitor the relationship between voltage and current is given as v=(jx)i , where v= voltage i= current jx=capacitive reactance
When excessive voltage is applied to a capacitor it will break down What factor of the capacitor has the greatest effect on breakdown voltage?
The dielectric material between the plates.
Why voltage across capacitor goes to zero when wires connected to each terminal of charged capacitor are brought into contact?
The voltage goes to zero because a current path has been created between the positive and negative elements of the capacitor, discharging the stored charge and putting both the anode and cathode of the capactor at the same electrical potential. Thus, no voltage difference between them, which is why the voltmeter reads zero.
Will a capacitor lower voltage?
A: As soon as a DC voltage is applied the capacitor is a short or no voltage
How is make capacitor?
Capacitor is nothing but a storage device. It has a dielectric media in between the two electrodes. the nature of the capacitor is charging and discharging the voltage.
Why is voltage rating of a capacitor important to the user?
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.
What is meant by a capacitor's working voltage?
A capacitor's working voltage is the maximum voltage that the device can take without danger of breaking down the insulation between the plates. Above the working voltage, the insulation begins to deteriorate and the capacitor may short, explode, or simply stop working depending on the design of the part.
What is the Difference between supply voltage and input voltage?
no difference...
Can capacitor increase low voltage to high voltage?
yes a capacitor can improve voltage by improving power factor
