Why connect a 100 Ohm resistor to the two terminals of a capacitor If the voltmeter doesn't turn to zero would be better to use a larger resistor?
We can guess that the resistor is used for discharging the capacitor's plates. Generally we short the two terminals on a capacitor to discharge it fully. A resistor will take more time to do this than shorting-out the terminals: the higher the resistance, the longer the time that will be taken to discharge a capacitor fully.
How capacitor act like resistor?
capacitor acts as resistor because it has some resistace alos.
What is the time constant of a series rc circuit consisting of a 2000 ohm resistor and a 10 microfarad capacitor?
2*103*10-5 = 2*10-2 Seconds = 20 milliseconds
What is passive capacitor?
A capacitor is passive like a resistor is passive it performs no active amplification.
What is function of capacitor in 555 IC?
the capacitor and its associated resistor set the time constant.

How do you prevent shock by capacitors?
Discharge the capacitor, normally with a resistor accross the terminals (Calculated size)
What is the time constant of a .05 microfarad capacitor and a 200 kilo ohm resistor connected in series?
The time constant of a 0.05 microfarad capacitor and a 200 K ohm resistor in series is simply their product, 0.05 times 200,000, or 10,000 microseconds, or 10 milliseconds. (Farads times ohms = seconds)

When a circuit consists of a capacitor and a resistor in series with a voltage source and the voltage across the resistor becomes zero then the capacitor is?
fully charged.
Why do resistor voltage decrease while capacitor discharges?
The reason why resistor voltage decreases while a capacitor discharges is because the resistor acts like a source of electrical energy. As the capacitor discharges, it draws energy from the resistor, which causes the voltage across the resistor to decrease. This is because the capacitor is acting like a drain, and is taking energy out of the resistor, thus causing the voltage across the resistor to decrease. The resistor and capacitor work together in order to create a discharge circuit. This is done by connecting the capacitor to the resistor, and then to a voltage source. The voltage source supplies the energy to the resistor, and then the resistor transfers this energy to the capacitor. As the capacitor discharges, it takes energy from the resistor, which causes the voltage across the resistor to decrease. In order to understand this process better, it is important to understand the basics of Ohm's Law. Ohm's Law states that the voltage across a resistor is equal to the current through the resistor multiplied by the resistance. As the capacitor discharges, it takes energy from the resistor, which means that the current through the resistor decreases, and therefore the voltage across the resistor will also decrease.
