A resistor is heated by any power source, AC or DC. Voltage is joules per coulomb. Current is coulombs per second. Voltage times current is work in watts or joules per second. This is heat transfer, and is manifest by the resistor getting warm. Actually, any device that dissipates power will get warm. Some of the heat energy is consumed in doing other work, such as in producing light in a light bulb, but much of it also produces heat, also such as in producing heat in a light bulb.

What is a slc500?
A current limiting resistor for ac devices.
What is the phase difference between the current through the resistor and inductor in an AC circuit?
The phase difference between the current through the resistor and inductor in an AC circuit is 90 degrees.
What happen when ac current passes through resistor?
it resists the flow of cuurent
Can rheostat run on AC current and DC current?
Yes, a rheostat can be used with both AC and DC currents. The rheostat's variable resistor can be adjusted to control the current flowing through a circuit, regardless of whether it is AC or DC.
How a ballast resistor convert DC into ac?
A resistor, by itself, can not convert DC into AC.
What is the average value of the alternating current (AC) in the circuit?
The average value of the alternating current (AC) in the circuit is calculated by finding the root mean square (RMS) value of the current waveform. This value represents the equivalent direct current that would produce the same amount of power dissipation in a resistor as the AC current.
What value of resistor would take you from 18v ac to 3.3v ac?
sorry - no can do. The value of a resistor is dependent upon the amount of current flowing through it. To drop the a.c. voltage as you have stated would require a drop-down transformer.
What happens to the resistance of a common ohmic resistor when it is heated?
When a common ohmic resistor is heated, its resistance typically increases.
When an inductor and resistor are connected in parallel by how many degrees is the current flow through the resistor out of phase with the current flow through the inductor?
When a resistor and an inductor are both connected to an AC supply, the current in the resistor is in phase with the voltage, while the current in the inductor is a quarter-cycle (90 degrees) behind. Supposing they both draw 1 amp on a 12-volt AC supply. The resistor will dissipate 12 watts, while the inductor will dissipate no power. Any power that enters the inductor comes back to the generator in a later part of the cycle. But the current drawn from the supply is 1.414 amps, so this would be a load with a power factor of 0.707.
Is a resistor and rectifier the same?
No, a resistor and a rectifier are not the same. A resistor is a passive electrical component that opposes the flow of current, thereby controlling voltage and current in a circuit. In contrast, a rectifier is an active component that converts alternating current (AC) to direct current (DC) by allowing current to flow in only one direction. While both are essential in electronic circuits, they serve different purposes.
When a capacitor and a resister are connected in parallel how many degrees out of phase are the current flow through the resistor and the current flow through the capacitor?
When a capacitor and a resistor are connected in parallel, the current through the resistor and the current through the capacitor are 90 degrees out of phase. The current through the resistor is in phase with the voltage across it, while the current through the capacitor leads the voltage by 90 degrees. This phase difference results from the reactive nature of the capacitor, which affects how current and voltage relate in AC circuits.
In roughness measureing system what is RMS value?
RMS value is defined as "The amount of ac supply required to make same heat effect in resistor , which is made by dc current, in that resistor"
