In the electrical circuit the higher the voltage the lower the?
Amps Ohm's law states the current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
If the decrease voltage and the resistance stays the same is current increased or decreased?
This question follows Ohm's law which states, "Current is directly proportional to the applied EMF (voltage) and inversely proportional to the current in the circuit. <<>> decreased
What is ohm low?
v=ir Ohm's law states that , in a dc circuit the current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. It has the formula V=IR where I is the current and R is the resistance.
If power is constant increasing the voltage will increase or decrease current?
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
Working principle of generator?
An electric generator is a device which converts mechanical energy to electric energy. An electric generator basically works on two principles, they are:- 1. Electro magnetic induction: This was first discovered by Michael Faraday this law states that when a electric conductor moved through a magnetic field cutting the electro magnetic waves, a electric charge is produced in the conductor. 2. Flemming's right hand rule: Place your thumb finger, index finger, and your middle finger in such a way that all the three are mutually perpendicular to each other. Here if your thumb points the thrust or force and index finger points the electro magnetic field then your middle finger points the direction of induced current. An electric generator consists of a electromagnet or a huge horse shoe magnet in which an armature is enclosed. The armature is made of copper coils. Now when the armature is rotated, it cuts the electro magnetic waves generated by the magnet and hence as a result of electro magnetic induction electricity is generated in the armature and the direction of the induced current can be found out using the Flemming's Right Hand Rule. And how the electric current produced later is stored and carried out differentiates between AC generator and DC generator
What is stated by the law universal of gravitation?
The Law of Universal Gravitation is derived from observations by Isaac newton, called induction. It states that, "Any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them."
What is Farady's law?
Three laws of electromagnetic induction, and two laws of electrolysis, all proposed originally by English physicist Michael Faraday. The laws of induction are: (1) a changing magnetic field induces an electromagnetic force in a conductor; (2) the electromagnetic force is proportional to the rate of change of the field; and (3) the direction of the induced electromagnetic force depends on the orientation of the field. The laws of electrolysis are: (1) the amount of chemical change during electrolysis is proportional to the charge passing through the liquid; and (2) the amount of chemical change produced in a substance by a given amount of electricity is proportional to the electrochemical equivalent of that substance.
Which law states that voltage is induced in a circuit whenever the flux linking the circuit is changing and that the magnitude of the voltage is proportional to the rate of change of the flux linkage?
Faraday's Law.
What is lenz law of electromagnetic induction?
Lenz's law states that 'for a current induced in a conductor by a changing magnetic field, the current is in such a direction that its own magnetic field opposes the change that produced it.'
What are 5 example of force?
polarized atomic regions (a magnetic substance) electron-induced magnetism (induction) radio-induced magnetism (radio waves induce current on a conductor that in turn is creates electron induced magnetism) reverse-magnetostriction (the opposite of the effect that states magnetism causes metal to change shape on the atomic level) a flawless LRC circuit

What happens when a magnet is move back and forth inside a coiled wire?
HD cameras will allow your videos and Photography have a better resolution. You can then view them in HD on your HDTV.
How Michael Faraday discovered electromagnetic induction?
Move a magnet into a coil, and a voltage is induced into that coil, causing a galvanometer to deflect. Withdraw the magnet, and the galvanometer will deflect in the opposite direction, indicating that the induced voltage depends upon the direction of motion of the magnet.
Define the term induced current?
a current can be induced by changing the area of a coil in a constant magnetic field. By Faraday's Law: the induced current is proportional to the rate of the change of flux in a loop of wire. With magnetic flux being defined as the product of the magnitude of the magnetic field and the area of the loop. The direction of the current is found from Len's Law: The induced current produces an induced magnetic field that opposes the change of flux causing the current.CommentYou don't induce a current, you induce a voltage. And Faraday's Law states that the induced voltage, not current, is proportional to the rate of change of flux! If the coil is open circuited, a voltage is still induced into the coil but no current will flow. For current to flow, the coil must be connected to a load (or short circuited), and this current is dependent upon the values of the induced voltage and the resistance of the load.
When was United States Naval Academy Induction Day created?
United States Naval Academy Induction Day was created in 1845.
What did the plan call for?
It called for the states to have proportional representation.
