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 is the importance of an electrical switch?
It allow you to disconnect power to an electrical device with the flip of a switch.
What is the difference between electrical engineering and electrical power engineering and what bachelors degrees that will allow me to get a masters degree in mechatronics engineering?
Electrical engineering is low voltage, logic circuits, communications etc. Power engineering is electrical transmission and the like.You want EE.
What is an electrical conductor and an electrical semiconductor?
Conductors are substances that allow flow of electricity through them. Although some electricity is lost in the form of heat, yet is negligible. Eg: silver gold copper iron Semiconductors are elements that allow electricity partially. For example they allow 50 percent and stops the rest. Eg: silicon germanium
How do dams help produce hydroelectric energy?
Dams produce electrical energy by utilizing the energy in the water stored in an elevated lake. Outlets in the dam allow water to escape down a pipe, trading potential energy for kinetic energy, ie, as it falls it moves faster. At the bottom of the dam, the fast moving stream of water enters a turbine where the it hits the blades of the turbine and makes it spin rapidly. The spinning turbine is connected to a generator, a rotating machine with magnets that converts the energy of rotation into electrical energy, usually AC. The AC voltage is run into a transformer to convert it to high voltage (higher voltage is better for long distances) and sent on towers to where it is needed.
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.
Energy that will help prevent energy shortages and allow fossil fuels to last longer?
electrical energy
Materials that allow electrical charges to pass through them without electrical resistance and without loss of energy are called?
Superconductors
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 does a circuit board 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 energy changes take place when a light switch is turned on?
mechanical to electrical to light 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

Why you do soldering?
Soldering is used to connect two or more than two pieces of metal or electrical components like wire, capacitors, resistors etc. together to allow current flow through the soldered joint. The word solder comes from the Middle English word Soudur, Latin word solidare which means "to make solid". Soldering has a lower melting temperature below 450°C (842°F). More info: ipctraining.com
