Should you worry about capacitor lead length in a circuit?
Capacitor lead length is a consideration in a circuit when the frequency involved is sufficient the make the parasitic capacitance and inductance of the leads important.
How do you find the polarity of capacitor wikianswerscomQHow do you find the polarity of capacitor?
To determine polarity in CAPACITORS:Electrolytic capacitors are often marked with a stripe. That stripe indicates the NEGATIVE lead.If it's an axial leaded capacitor (leads come out of opposite ends of the capacitor), the stripe may be accompanied by an arrow that points to the negative lead.Sometimes, you can look to the length of the leads as an indication of polarity. The positive lead is usually longer but be careful if you're reusing old or 2nd hand capacitors - the leads may have been trimmed.Tantalum capacitors are often marked with a '+'sign.http://www.westfloridacomponents.com/polarity.html
What happens to the time taken for the capacitor to charge and discharge when you increase the resistance in the circuit?
It increases. The time constant of a simple RC circuit is RC, resistance times capacitance. That is the length of time it will take for the capacitor voltage to reach about 63% of a delta step change. Ratio-metrically, if you double the resistance, you will double the charge or discharge time.
What should we do to increase the capacitance of a capacitor?
Not much if it is a fixed capaitor. If it is a variable capacitor, rotating the shaft to mesh the two sets of plates more closely will increase the capacitance.
Advantages of bank capacitor?
Capacitor banks can improve the power factor if the load is leading, which is unusual. Typically in substations capacitor banks are employed to reduce over voltage.

Capacitor lead length is a consideration in a circuit when the frequency involved is sufficient the make the parasitic capacitance and inductance of the leads important.
Does lead length matter in capacitance of a capacitor?
In general the length of the leads contributes only a negligible amount to the capacitance of a capacitor. However at high enough frequencies excessive lead length can contribute an undesirable amount of parasitic inductive reactance, causing problems in circuit operation.
What is capacitor LS?
The distance between the leads (lead spacing) on a radial capacitor
Whats the highest voltage increase i can make when replacing a Capacitor?
you cannot increase the voltage by replacing a capacitor. A capacitor is a passive components it has no gain.
What is the function of a capacitor's leads?
To connect it to the circuit.
Why should a capacitor never be held by its leads?
A capacitor is designed to store energy over time and then release it nearly instantaneously. If you are holding it by its leads it could discharge and kill you.

The capacitive reactance of a capacitor increase as?
The capacitive reactance of a capacitor increases as the frequency decreases.
How do you increase the value of a capacitor?
A: Any additional capacitor added in parallel will effectively increase to total capacitance by that value. Note that additional capacitor added must have the same voltage rating as the other
Can you replace a 470uf 10v capacitor with a 470 25v 105c high temp radial leads capacitor for a digital tv converter box?
Yes, as long as there is room to mount the larger capacitor. A better replacement might be a 470uF 16v capacitor, which should be smaller than the 25v cap. If necessary, insulating tubing can be put on the leads & the cap can be mounted off the board, or at an angle to the board. Remember to observe polarity when connecting the capacitor leads to the board. Note the orientation & markings on the old capacitor before unsoldering it.
What will happen if the capacitor is removed from the DC charger?
It will increase the ripple factor that the capacitor is in the circuit to smooth out.
Function of dielectric in a capacitor?
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
