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 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).
What is series dropping resistor?
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
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.
Who invented the resistor?
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
Describe the purpose of the coloured bands on a resistor?
The purpose of colored bands on a resistor is to tell whoever is installing the resistor the amount of resistance that particuliar resistor has.
