What is the power consumption of a capacitor or inductor?
Capacitors and Inductors theoretically consume no power. In real life, they only consume power because they have an internal resistance.
What is resistance start capacitor run?
most capacitors will measure infinite resistancestarting capacitors are used to set up a rotating magnetic field by phase shifting a coil in a single phase motorwhen the motor gets up to speed a centrifugal switch will disconnect the capacitorthis happens at a random time and can leave the capacitor with a charge easily 4x the applied ac voltage (+/-1,000V)so some capacitors rated as starting capacitors will have an internal bleeding resistorGas discharge lamp ballast capacitors sometimes have discharge resistors.Microwave ovens have capacitors usually in a voltage doubling configuration(+/-20,000V) most have an internal bleeding resistor.Never rely on this resistor being intact or even present.It can have fatal consequences.the internal resistors are sized to discharge the capacitors in tens of minutesTc = R * C ( seconds = ohms * farads )
Is it desirable for a battery to have a high internal resistance?
No, it is desirable for a battery to have a low internal resistance.
Actual internal resistance of 1.5 volt battery?
The value of internal resistance of 1.5 volt battery is 0.5 ohms.
What is meant by the internal resistance of a battery?
There is internal resistance in a battery because a battery is not an ideal voltage source. It may be close, but it is not ideal. As a result, analytically, there will be some series resistance, resistance which places a limit on the maximum current that the battery can provide. While no battery is ideal, most are sufficiently ideal to not require any consideration of the internal resistance. If your circuit is dependent on the internal resistance of a battery, then it is probably not well suited for that application.
Why it is advisable to remove the source and complete the circuit by internal resistance or by a link instead of short circuiting the terminals of the supply?
Because many electronics, like power supplies, have internal energy storage in the form of capacitors. If you were to short the terminals, you would be shorting out the internal capacitors and thus creating a potentially hazardous situation. "Completing the circuit by internal resistance" allows the energy stored in the internal capacitors to bleed off slowly because the internal resistance is larger than a short.
How do you determine the internal resistance of capacitors?
The best way is to check the data sheet and see if ESR (equivalent series resistance) is listed.
What is an reactance?
it is a internal resistance of the devices like as capacitor and inductorCommentAs 'resistance' has a very specific meaning, I suggest that the above answer should read: 'It is the opposition of devices like capacitors and inductors (to the flow of current).'

When two capacitors connected with resistance in series?
(r+(c/2))
Do meters usually have a high or low internal resistance?
It depends on the application. Voltmeters have a high internal resistance, while ammeters have a low internal resistance.
Is it desirable for a battery to have a high internal resistance?
No, it is desirable for a battery to have a low internal resistance.
Define Internal Resistance?
The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
How resistivity effects internal resistance of a cell experiment?
Resistivity effects internal resistance of a cell experiment by not allowing the cell to react. Internal resistance experiments are performed in advancing physics classes.
Do Dead batteries have high internal resistance?
yes, batteries have high internal resistance. The higher the resistance the lower power you get out of the batter. Therefore if you no power you have very high resistance.
What is internal resistance?
it is a type of resistance which inbuilt in voltage source
