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 is the uses of power lines?

They allow electrical energy to flow from the source (the power plant) to its destination (homes, businesses, etc)


What sentence can I use for Electric Circuits?

Electric circuits can be described as closed loops that allow electric current to flow, enabling the operation of various electrical devices. They consist of components such as resistors, capacitors, and power sources, which work together to control and manage the flow of electricity. Understanding electric circuits is essential for designing and troubleshooting electrical systems.


What is the importance of an electrical switch?

It allow you to disconnect power to an electrical device with the flip of a switch.


Does the transmission of electric energy required electrical conductors between the source and receiver?

Yes, the transmission of electric energy typically requires electrical conductors, such as wires or cables, to facilitate the flow of electricity from the source to the receiver. These conductors allow electrical current to travel efficiently while minimizing energy loss due to resistance. In some cases, alternative methods like wireless power transmission exist, but they are less common and often limited by distance and efficiency.


What is the composition of a resistance box?

A resistance box typically consists of a series of resistors arranged in a specific configuration to provide a range of resistance values for testing and calibration purposes. The resistors can be made from materials such as carbon, metal film, or wire-wound elements, and they are usually housed in a sturdy, insulated enclosure. The box features a set of switches, knobs, or terminals that allow users to select or combine different resistances as needed. This device is commonly used in laboratories and educational settings for experiments involving electrical circuits.

What are resistors?

A resistor is an electrical device that limits current in a circuit. It converts electrical energy into thermal energy (heat), and drops voltage. Conductors in an electrical circuit allow current to flow through them will little resistance. The medium in a resistor, the resistive material, is not a good conductor, and will "resist" the current that wants to flow through it. This is how it limits current in a circuit. A resistor is rated according to its resistance and it ability to dissipate heat. It will be rated in ohms of resistance and in watts. A one ohm resistor will allow one amp of current to flow through it when one volt is applied across it. It will generate one watt of thermal energy, which it will have to dissipate as heat.A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor.

What is the source of the electrical energy in the brain?

The source of electrical energy in the brain is the movement of ions, such as sodium and potassium, across the cell membranes of neurons. This creates electrical impulses that allow for communication between brain cells.


What do circuit boards do?

A circuit board is the pathway for electrical currents to path through to send messages to other connectors. A circuit board consists of capacitors and resistors which allow and resist electric signals.

What does to allow energy of electricity to flow mean?

It means that you let an electrical current flow. The current will, of course, carry energy.


What is a non-conductive resistor?

non-conductive resistors are resistors made from materials which do not allow the passage or flow of electric current through them.


What is the advantage of battery power?

Batteries allow to seperate a device which requires electrical energy from a direct source of it.


What working of resistor?

The main power producers in an electrical system are the battery and alternator. The alternator puts 14 volts of alternating current into the electrical system and resistors. The resistors only allow a fraction of the AC voltage produced to reach the systems' sensitive components


What are the different kinds of resistor?

There are various forms of resistors used for electronic circuits. You can divide it in mainly two basic types:Fixed Resistors: The resistors that come with two wires are listed in this resistor type. These kinds of resistors do not allow you to change the resistance.Variable Resistors: These types of resistors allow you to change the resistance using the resistance using the knob.Some other types or resistors are as following:Carbon Film ResistorMetal Oxide Film ResistorPrecision Metal Film ResistorWire Wound Resistor (WWR)Power Film ResistorPrecision Wire Wound ResistorHigh Power Wire Wound ResistorPhotocellLight Dependant Resistor (LDR)Voltage Dependant Resistor (VDR)
