What is time constant of capacitor when resistance is zero?
Time constant in an RC filter is resistance times capacitance. With ideal components, if the resistance is zero, then the time constant is zero, not mattter what the capacitance is. In a practical circuit, there is always some resistance in the conductors and in the capacitor so, if the resistance is (close to) zero, the time constant will be (close to) zero.
What is bleeder resistor?
They are resistance connected in parallel with high voltage power supply for the purpose of discharging the energy stored in filter capacitance when the equipment is turned off.
How do you calculate contact resistance?
Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.
What is the difference between on and off state resistance?
On Circuit Resistance = Close to the total load Resistance. Off Circuit Resistance = Near Infinitive High Resistance.
What is Hot Resistance?
Hot resistance is your total resistance you can have with out exceeding your wattage limit
What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
Why are you using bleeder resistor in LC filter?
In LC filter , Bleeder resistance is connected in Parallel with the load to maintain the minimum current through the choke and so the performance of the Filter improves.
What is the roll of bleeder resistance in LC filter circuit and what will happen if the bleeder resistor is not used in circuit?

What causes high pool filter pressure?
Water is meeting more resistance as it is making its way through the filter media usually indicating that the filter needs to be cleaned. Some times in the case of sand filters it indicate that the sand needs to be replaced.
How does a capacitor act as a filter?
The cutoff frequency of filter depends upon the value of capacitor and resistance. Therefore, below cutoff frequency or above this frequency, capacitor allow to pass all other frequencies.

How do you check the fuel filter on a 1996 cutlass supreme?
if it has more then 20,000 miles its bad or blow through it no resistance means its good
What is the effect of load resistance on ripple voltage in presence of filter capacitor?
Ripple voltage, in the presence of a filter capacitor, is inversely proportional to load resistance. If the load were zero (resistance infinite), then there would be no ripple voltage. As the load increases (resistance decreases), the ripple voltage increases. The ripple waveform will appear to be sawtooth, with the rising edge following the input AC from the diode's conductioin cycle, and with the falling edge either being linear or logarithmic, depending on load. If the load is resistive, without a regulator, the falling edge will be logarithmic. If the load is constant current, such as with a regulator, the falling edge will be linear.
Does air-filter size matter on carburetor engines?
Yes. Airflow through the filter is determined by area and resistance. The bigger the filter area, the smaller the amount of air that has to pass through each part becomes. With a big filter area, and each part only having to let through a little air the air flow through the filter can be bigger. And allowing more air into the engine can make it run better.

How do you check fuel filter for 99 Ford Windstar LX?
The only real test for the fuel filter is to blow into it - if there's much resistance, it's plugging up.Since it's out, you might as well replace it.See "Related Questions" below for more
