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 else can I help you with?
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.
What component in an electrical circuit provides resistance?
The component in an electrical circuit that provides resistance is called a resistor.
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 device is used to adjust the flow of electrical current?
A device used to adjust the flow of electrical current is called a resistor.
Does a resistor reduce current or voltage in an electrical circuit?
A resistor reduces the flow of current in an electrical circuit, which in turn affects the voltage across the resistor.
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.
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 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.
How does a resistor reduce voltage in an electrical circuit?
A resistor reduces voltage in an electrical circuit by converting some of the electrical energy into heat. This process slows down the flow of electricity, resulting in a decrease in voltage across the resistor.
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 is the name for an electrical load that converts electrical energy into heat energy?
The name for an electrical load that converts electrical energy into heat energy is a resistor. Resistor works by resisting the flow of electricity through a circuit, which in turn generates heat as a byproduct.
