It is a component or substance which reduces the flow of electricity in a circuit. Their will be one in your mobile phone charger to stop 240/230 volts being routed into your phone( which would probably charge it very quickly but then it would blow up!) Also a resistor is the opposite of a conductor i.e something that resists conducting electricity.

What does R mean in an electrical circuit?
it's generally the resistance. its generally the energy dissipiating component called Resistor
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
Why are resistors called resistors?
Resistors have resisting power(resists the electric power).Due to having the resistive property, the name resistor is given to such electrical device.
Why is a resistor called so?
I resistor is called so because it provides electrical resistance (measured in ohms). Electrical resistance describes how an electrical conductor (a wire) opposes the flow of an electrical current (flow of electrons). To overcome this opposition a voltage (a energy) must dropped (used) across the conductor (wire).
What is a resistor that can be adjusted between minimum and maximum by turning a dial is called a what?
It is a variable resistor. Basically, the same as when you turn up or down the heat on an electrical oven or radio.
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.
What is s device that interferes with the flow of an electrical charge?
You cannot 'slow' the flow of current in a wire. What you can do, however, is to reduce its value, or to limit its upper value. The device that will do this is a resistor. If, by your question, you are asking how to reduce the rate of change in its magnitude, then you can use an inductor.
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.
How do you electrical powers?
Voltage x current. In a resistor for example it is the voltage drop across it that is relevant, it may be part of a circuit.
What does R mean in an electrical circuit?
it's generally the resistance. its generally the energy dissipiating component called Resistor
Who discovered Resistor?
Resistance, and therefore resistors, are a part of any electrical conductor. They were not created but rather, discovered and put to use in electrical and electronic circuits.
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.
