when you think of electricity and resistance think of it as water in a river and rocks in a river. The water being the electricity and the rocks being the resistance. when water in a river flows and then come across rocks that block the water from flowing constantly, it slows down the water. therefore when electricity is flowing through a circuit with resistance, when it hits the resistors it slows the flow of electricity.

Why the resistor does not have polarity?
they do not have any electrical property that is polarity sensitive
Resistors allow electrical energy to be changed to other forms of?
All a resistor does is use electrical energy, converting it to heat. so a 10 ohm resistor with 5 volts across it will dissipate 2.5 watts. this will come out as heat, ie, the resistor will get hot.
What component resists flow of current in an electrical circuit?
transistor
What happens to the resistor when there are more components?
Nothing happens to the resistor other than it may interact with the other components so as to perform a desired function.
What happens if you remove emitter resistor in RCcoupled amplifier?
what happens if we remove Rc in RC coupled amplifier
Who invented the resistor?
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
What the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
What is a resistor What does it do in a circuit?
A resistor is a passive two-terminal electrical component that limits the current flowing in electrical or electronic circuits.
When and by who were resistors made?
Otis F. Boykin invented the wire precision resistor and the electrical resistor. In June 1959, he got the first patent for the wire precision resistor and in June 1965, he got his patent for the electrical resistor.
What are the colors of a resistor and why are they there?
There are many colours for resistor rings but the reason that we have them is to help the resistor reduce the electrical current that is passing through.
What is resistor in physics?
A resistor is a component of an electrical circuit that resists the flow of electrical current. A resistor has two terminals across which electricity must pass, and is designed to drop the voltage of the current as it flows from one terminal to the next. A resistor is primarily used to create and maintain a known safe current within an electrical component.
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.
What does a resistor do in in a circuit?

What is the name for an electrical load that converts electrical energy into heat energy?
A Resistor or Resistance
What is a ballast resistor?
A ballast resistor is an electrical resistor whose resistance varies with the current passing through it, thus maintaining a constant current.
What slows down current and converts electrical energy into other forms of energy?
That sounds like a resistor. However, please note that "slow down a current" is not a very accurate description of what happens. What the resistor does is take energy away from the current.
What changes electrical energy to heat energy?
A resistor.
