A resistor works by limiting the current that goes through it.
When current is limited, then voltage across the resistor also changes.
We use many forms of resistors in our normal day.
Lightbulbs are infact all resistors in one way or another.
When the filament in a lightbulb heats up, the resistance increases. When resistance increases, the current is reduced. In the end, the current has been reduced so much that it can no longer carry on heating up the filament. The bulb is then thermally stable and shines for our pleasure.
General purpose resistor is used to resist the current flow.the common resister is general purpose resister.
non-conductive resistors are resistors made from materials which do not allow the passage or flow of electric current through them.
A filament bulb resistor is the common type of light bulb. It contain a thin coil wire called filament. It produces light as a result. It is made mainly from the element tungsten. The metle tungsten has very high melting point and it is a good conductor of electric current
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
The electric current is given by: I = V/R
Resistor is a component of an electric circuit that resist the flow of direct or alternating electric current . It can also limit or divide the current, reduce the voltage, protect an electric circuit, or provide large amounts of heat or light.
The resistor allows current to enter the electromagnet in an electric motor. The resistor regulates the amount of current that enters the electric motor.
When an electric current flows through a resistor, the resistor resists the flow of the current, causing a decrease in the current. This decrease in current is proportional to the resistance of the resistor, as described by Ohm's Law.
It resist the flow of current according to the resistance value.
Adding a resistor to an electric circuit reduces the current flow by impeding the flow of electrons. The resistor increases the resistance in the circuit, which in turn decreases the amount of current that can pass through.
No, a resistor is not considered a conductor. Resistors are components that impede the flow of electric current, while conductors allow electric current to flow easily.
General purpose resistor is used to resist the current flow.the common resister is general purpose resister.
A LDR or light dependant resistor is a resistor that works when light is not shining on it, so if there is light on it it will not resist a current, you can also get them to work the other way.
An electromagnet is not a resistor; they are two different components in an electrical circuit. An electromagnet uses electric current to create a magnetic field, while a resistor resists the flow of electric current, which causes a voltage drop across it.
Current moving through a resistor causes it to heat up because of the flowing electrons bumping into the atoms in the resistor.
No, but it has resistance. Everything has resistance to current flow. It's sole purpose is not to resist current. It likely has resistors in it though.
Limits current flow and drops voltage.
