What are 3 things required to induce voltage?
A magnetic field, a conductor and movement.
What are advantages of voltage divider bias over the other types of biasing ci?
You can use more than one type of voltage divider in it. It can sometimes get mixed signals with all the things going on.
Why dc shunt generator can not induce any voltage with rated speed?
Two things could have occurred. (1) wrong direction of rotation causing loss of residual magnetism or (2) loss of residual magnetism over long period of no use. can be remedied by "flashing" the shunt field winding howlumf
What is power cable size for 1 kw 1 phase motor over 500 meters?
It depends on the voltage that the motor needs, because a higher voltage requires less current for a given amount of power. Also a higher voltage can tolerate a higher voltage drop. So there are two things that lead to a thinner wire when the voltage is higher.
Which one is better potentiometer or voltmeter?
Neither is better or worse than the other. A potentiometer is an adjusting device usually for voltage while a voltmeter is a device for measuring the voltage. They are just two different things.
What are 3 things required to induce voltage?
A magnetic field, a conductor and movement.
What three things effect the value of the applyed voltage in a conductor?
Lenght, diameter and material of the conductor.
How do you make electricity with a wire and a magnet?
If a wire - or in fact, any conductor - moves in a magnetic field, a voltage will be induced in the wire or conductor. To actually get electricity for something useful, quite a few additional things are required. Do some reading about generators, to see how they are built.
Is sugar a conductor or non-conductor of heat?
Everything conducts heat and electricity (if the voltage is high enough). Some things do it well, some things do it poorly. Sugar is one of those things that does it poorly. Actually not every thing conducts electricity such as rubber even if at high voltage
How many things are needed to create a current?
A difference of potential (voltage) and a conductor connected to the voltage source will cause current flow. Not that you'd want to "short out" a voltage source with a piece of wire, but just the source of voltage and the conductor would permit current to flow. If you took a piece of wire and touched it to the terminals of a good battery, current would flow. It takes just those two things to create a current.
What is electromagnetic induction?
Electromagnetic Induction mainly deals with the ways that energy is shifted about between Electric and Magnetic fields in various circumstances. Here are some major examples:1. A moving Electric Current Induces a Magnetic field: Electromagnets.2. A moving conductor in a magnetic field Induces an Electric Current: The Dynamo or Electric generator.3. An Electrified Conductor in a Magnetic field Induces motion in the Conductor: The Electric Motor.Related Information:Albert Einstein's considerations of inductance, an Electrified length of conductor moving through a Magnetic Field in an empty volume of space, led him to his theory of Special Relativity.
What affects the resistance of an electric conductor?
The material from which the conductor is made, the length of the conductor, the diameter of the conductor and the temperature of the conductor are all things that impact its resistance.
If an electrical current passes through a conductor what two things are generated?
If an electrical current passes through a conductor, there is an induced voltage (because no conductor has perfectly zero ohms), resulting in power dissipation, and there is a magnetic field, which can interact with other conductors in the vicinity of the first.
What should you compare our brain to a computer or an orchestra conductor?
Orchestra conductor, because our brain is doing so many things at once. (An orchestra conductor does many things at once).
What other things can be a conductor?
a paperclip
How does transforms works?
A transformer works on the principle of electromagnetic induction. Let's do a bit of review and then pull some things together. Any conductor through which current is flowing will have a magnetic field around it. When the current begins to flow, the field will build. Conductors with a changing current in them, with an alternating current (AC) flowing through them, will have a changing magnetic field around them. The field will arise and take form, then collapse. It will then arise again with the opposite polarity, and then collapse. This alternating field, which is a direct result of the alternating current, can be set up near another conductor to induce a voltage in that other conductor. The magnetic field around the first conductor is said to "sweep" the second conductor and induce that voltage in it. This is electromagnetic induction, and is the principle on which transformer action occurs. If we wind a coil of wire around a ferromagnetic core, the core will facilitate the "flow" of the magnetic field that arises as AC is applied to the winding. The addition of a second (secondary) winding around the core in the vicinity of the first (primary) winding will allow an optimum amount of "sweeping action" (magnetic coupling) to occur between the two windings. And if we tinker a bit with the number of turns in the windings, we can get stepped up or stepped down voltages as a result of the transformer action in the device.Transformer is a type of machine which is used to step up or step down the voltage.and works on the principle of mutual induction.according to which voltage can be induced in a winding that is electrically isolated from the winding connected with source...
