What does a pencil resistor do?
A Pencil Resistor is a thing that gives energy to something or anything that needs energy.
What does it mean when you say that energy is lost in a resistor?
When we say that energy is lost in a resistor, it really means that electrical energy has bee transformed into other forms of energy. These other forms of energy do not easily get changed back into electrical energy.
What is an example of a resistor that transforms electrical energy to light energy?
A lightbulb filament.
How does a windmill store energy?
It isn't meant to store energy. It simply transforms the wind energy into other forms of useful energy. Of course, it may briefly have some rotational (i.e. kinetic) energy stored, but that won't last long.
What causes a resistor to heat up?
The current through a resistor or for that matter any conducting medium is caused by flow of electrons. These electrons do not flow like a stream through the resistor or conductor but undergo repeated collisions with the vibrating atoms of the resistor, transferring their kinetic energy to them. This in turn increases the vibrational energy of the atoms and manifest itself as heat in the resistor/ conductor. In turn this results in reduced drift velocity of the electrons resulting in reducing the current , thus acting as a Resistor.

What Material Used For Electric Ovens using heating elements?
A resistor, which converts some electric energy to thermal energy!
What is the difference between a resistor and an inductor?
Both a resistor and an inductor are electrical components designed to impede the unregulated flow of electricity. Where they differ is that inductors store energy in their induction coils which forms a magnetic field that focuses energy by the principle of inductance. As electricity passes into the inductor, current will slowly rise to a specified level. A resistor simply impedes the flow of electricity according to its property, but does not store energy. It also does not control the rate at which the current changes, it just changes the current allowed to pass through.
What changes electrical energy to heat energy?
A resistor.
What do a resistor do in a circuit?
A resistor is a device that impedes or limits the flow of electrical current in a circuit. It converts the current's electrical energy into heat (thermal) energy. A resistor reduces the amount of energy in a circuit and pumps it out as a heat.

Is an resistor an conductor or a insulator?
A resistor is a conductor that dissipates some of the electrical energy fromthe current flowing through it. The energy dissipated by the resistor is(current through it)2 x (resistance)
How are power dissipated in a load or in a resistor?
Due to energy usage and/or the reduction in conductance (increase in resistance) in a given load or resistor, some electrical energy is lost through that component. As such, a proportional drop in current and voltage occurs.
Organisms store some of the energy from their food in their?
Cells store starch (which can be used for energy) in plastids.
How do you use resistor in a sentence?
I installed a resistor inline with my oil pressure sensor. The resistor in a circuit will usually disperse energy as heat.

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.
