Resistors cannot be charged in the same way capacitors can, as they do not store electrical energy. Instead, resistors dissipate electrical energy as heat when current flows through them, based on Ohm's Law. When a voltage is applied across a resistor, it allows current to pass, and the resistor converts electrical energy into thermal energy according to its resistance value. Thus, while resistors are integral to circuits, they don't store charge.
What else can I help you with?
A 10 microfard capacitor is charged through a 10 ohm resistor. How long will it take for the capacitor t fully charge?
If a 10 microfarad capacitor is charged through a 10 ohm resistor, it will theoretically never reach full charge. Practically, however, it can be considered fully charged after 5 time constants. One time constant is farads times ohms, so the time constant for a 10 microfarad capacitor and a 10 ohm resistor is 100 microseconds. Full charge will be about 500 microseconds.
Why is there a resistor on a 36v solenoid?
It reduces contact noise by reducing large voltage and current spikes as the relay is opened and closed, called a snubbing resistor. Before the age of solid state controllers, there were no resistors across the solenoids. The purpose of the resistor is to provide a charging voltage for the capacitors inside the solid state contoller. Without the resistor it would take several seconds for the (50,000 microfarad) capacitor to charge and the equipment to run. With the resistor the capacitors are charged while the solenoid is open and the equipment is ready to run at all times.
What is effect of charged and uncharged capacitor at the resistance of it?
The effect of a charged capacitor on the resistance in a circuit is that it can lead to a temporary increase in current due to the initial discharge when connected to a resistor, while an uncharged capacitor behaves as an open circuit at the moment of connection. Over time, as the charged capacitor discharges, the current decreases exponentially until it reaches zero, effectively behaving like a resistor with a time-dependent resistance. In contrast, an uncharged capacitor will not allow current to flow until it starts charging, resulting in a different initial resistance characteristic. Overall, the capacitor's state (charged or uncharged) influences how it interacts with the resistance in the circuit.
What is the function of a cement resistor?
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
Voltmeter is connected in parallel with resistor?
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
How can a capacitor be charged without using a resistor?
A capacitor can be charged without using a resistor by connecting it directly to a power source, such as a battery, which provides a constant voltage. This allows the capacitor to store electrical energy without the need for a resistor to limit the flow of current.
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.

Your ac been charged but dont blow cold air only hot this is in my 1999 olds bravada why?
could be something wrong with the resistor. mine was the opposite and it was my resistor that was going bad and finally went out. 135$ fix.

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.
How does the toast know when to pop the toast?
The toaster contains a variable resistor (timer knob on the outside) that changes the charge rate of the capacitors. When the capacitors are fully charged, the release the toast.
Is Light dependent resistor an example of resistor?
yes, a variable resistor

What to expect if a resistor is placed in a dc circuit with a capacitor?
when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"
What is capacitive effect in antenna?
The capacitive effect is an element's opposition to a change in AC voltage. The resistor will develop a positively charged current at it flows through a capacitor. This will prevent a change in the initial voltage.
