A brief change in electrical voltage in the neuron in response to stimulation is called what?
an action potential
Why frequency remains constant in transformer?
First we know that transformer is a statical electrical device that transfer electrical energy from one circuit to another circuit with out change its frequency .....it may be voltage or current is change simultaneosuly or separately .... and point is why does not change the frequency in the transformer because the there is no moving part in transformer....As we know that frequency is depends upon the rotation....
Does current affect electromagnetism?
Does current affect electromagnetism? No. Does current affect magnetic fields? Yes. The laws (Maxwell's Equations) pertaining to electromagnetism is constant and will not change regardless of current applied. However, Maxwell's equations does dictate that a change in current will essentially result in a change in magnetic fields. Current flow will produce a magnetic field perpendicular to the current direction.
What is the difference between a transformer and a rectifer?
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
What changes the voltage of a current?
First off, voltage and current are two completely different, yet related phenomenons.Kirchoff's law states that Voltage = Current * Resistance (V=IR. So, to change the voltage in a given circuit while keeping current constant, simply change the resistance.Open in Google Docs ViewerOpen link in new tabOpen link in new windowOpen link in new incognito windowDownload fileCopy link addressEdit PDF File on PDFescape.com
What is the instrument called that can change electrical voltage?
Electrical voltage can be changed by a transformer.
Can the voltage across a capacitor change instantaneously?
No, the voltage across a capacitor cannot change instantaneously. It takes time for the voltage across a capacitor to change due to the storage and release of electrical energy in the capacitor.
Whose law state that the induced voltage will produce a current that always act oppose the change that originally caused it?
It is the Micheal Faraday's law of electromagnetism.
A brief change in electrical voltage in the neuron in response to stimulation is called what?
an action potential
What are power converters used for?
Power converters are used to change electrical energy from one form to another. It could be changing the voltage or frequency or it could be switching between AC and DC.
What does chemical energy in a battery change to?
Voltage (increased charge concentration), and finally electrical energy.
What is the difference between an adaptor and a converter when it comes to electrical devices?
An adaptor is used to change the shape or size of a plug so it can fit into a different outlet, while a converter is used to change the voltage of an electrical device to match the voltage of the outlet it is being plugged into.

Does a transformer convert electrical energy into kinetic energy?
A transformer moves energy from one circuit to another. What form that energy takes is dependent on the apparatus being supplied with the energy. If going to a light, the energy is thermal and radiant. If going to a fan it is kinetic.
What is the function of shunt reator?
it is electrical device connected with high voltage current grids in order to protect the system from sudden drop or sudden change is voltage.
How does the voltage change each time you drop the magnet through the coil?
Each time you drop the magnet through the coil, it induces a change in magnetic field, which in turn creates a voltage in the coil. This voltage fluctuates as the magnet moves through the coil, causing a change in the electrical potential.
Define voltage in terms of electric potential energy and charge?
When unlike charges are moved farther apart, they gain electrical potential energy. Electrical potential difference is the change in potential energy per coulomb of charge. Voltage is the common name for electrical potential difference and is measured in volts (V). Electrical energy depends on the amount of charge and voltage. Electrochemical cells, or batteries, are a common source of voltage. We use voltmeters to measure potential difference. :)
