What is the effect on charging and discharging times if the capacitance is increased?
The charging and discharge time increases. R*C=T
IN case of lossy capacitor what effect would be on series equivalent resistor?
In case of a lossy capacitor, its series equivalent resistance will be large.
What negative effect could happen by over sizing a run capacitor?
Oversizing the capacitor can shorten motor life.
What is the effect of value of filter capacitor on ripple voltage?
Ripples in electricity are usually defined as small, unwanted variations due to direct current. The effect of using a filter capacitor in this environment may vary, but usually has a smoothing effect on the ripple.
What effect does increasing the timing capacitor have on the frequency out of an Astable 555 timer?
frequency drops
What is the effect on charging and discharging times if the capacitance is increased?
The charging and discharge time increases. R*C=T
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.
IN case of lossy capacitor what effect would be on series equivalent resistor?
In case of a lossy capacitor, its series equivalent resistance will be large.
What is the effect of bypass capacitor on frequency response?
Gain in a CE configuration of a BJT is collector resistance divided by emitter resistance, subject to the limit of hFe. The emitter bypass capacitor will have lower impedance at high frequency, so the gain will be higher at higher frequency, making this a high-pass amplifier.
How do you test a capacitor only by using a multimeter and two leads?
You can test a capacitor using a multimeter and two leads by placing the multimeter in ohms mode. It works best with a needle type meter, not a digital meter. Connect the leads to the capacitor and you will notice that the resistance pulses down, and then settles out at infinity. Reverse the leads, and you will notice the same effect, except that the pulse will be larger because the capacitor got charged in the opposite direction. Go back and forth. This won't be apparent for very small capacitors because the pulse is too short. Also, for electrolytic capacitors, they should only be charged in one direction, so you should start by discharging the capacitor and then connecting it in only one direction. Do not reverse the leads in this case. Just discharge and try again to see the effect. Try this for various capacitors. You will notice that the pulse duration is larger for larger capacitance.
What is effect of internal capacitance of transistor and resistor on propagation delay?
Internal capacitance of transistor increases propagation delay.Because charging and discharging of these capacitors will take more time which is not favourable.So always try to select transistors with minimum capacitance.
Effect of the capacitor to the low frequency waveform?
The differential equation for a capacitor is dv/dt = i/c. Set that up in a circuit and force an AC power source, such as sin(theta), and you will see that lowering the frequency will increase the equivalent resistance. I'll leave that exercise for you. The net result is that a series capacitor is a high-pass filter, while a parallel capacitor is a low-pass filter.
What is relationships of capacitive reactance to resistance?
when ever current passing through any two parallel transmission line than due to the dieletric property of conductor some what capacitance effect will be generate between them that phenomina called as capitance reactance/////////////////// that symply we can called capitance reactance is measure of capitance The reactance of a capacitor is its resistance.
Does a magnetic fIEld have an effect on a capacitor placed in between the plates?
Does a magnetic field have an effect on a capacitor when it is placed between the plates? Yes, a magnetic field between the plates of a capacitor would have some effect. Without more information it is difficult to determine how much.
Can a ignition switch short have an effect on the alternator charging the battery?
any short in the electrical system will have an effect on the charging system
How capacitor cancels inductive effect?
A capacitor try to leads the current while a inductor tries to legs the current so they cancels each other's effect ....
How you can reduce the effect of armature reaction?
by using capacitor
