What is a question about electric current?
describe PD
What relation between electric current and drift velocity?
The drift velocity of free electrons in a conductor is directly proportional to the magnitude of the electric current flowing through the conductor. This means that as the current increases, the drift velocity of the electrons also increases. The relationship is described by the equation I = nAvq, where I is the current, n is the number density of charge carriers, A is the cross-sectional area of the conductor, v is the drift velocity, and q is the charge of the charge carrier.
What 3 terms are used to describe electric pressure?
Voltage: This measures the electric potential energy between two points in a circuit. Electromotive force (EMF): It represents the push that drives the electric current in a circuit. Potential difference: This is the difference in electric potential between two points in a circuit, causing the flow of current.
How did Oersted discover the relationship between an electricity and magnetism?
Hans Christian Oersted discovered the relationship between electricity and magnetism in 1820 when he observed that an electric current flowing through a wire caused a nearby compass needle to deflect. This observation demonstrated that an electric current produces a magnetic field.
What is the Relation between temperature and current?
inversly proportional
What is the relation between current and thikness of conductor?
The thicker the conductor, the less the current that will flow through.
What is the relationship between the electric field and current in a circuit?
The electric field in a circuit is directly related to the current flowing through it. The electric field is what drives the flow of electric charge, which is the current. In other words, the presence of an electric field is necessary for current to flow in a circuit.
Who discovered the relation ship between electic current and resistance?
ohm
What term is used to describe the interaction between electrical energy and magnetism?
The term used to describe the interaction between electrical energy and magnetism is electromagnetism. This phenomenon occurs when an electric current produces a magnetic field and vice versa, as described by Maxwell's equations.
What is equation for current and frequency relation-ship?
There is no such equation. The main reason is that there is no relationship between current and frequency.
What is the diffrenece between electric charge and electric current?
Electric charge is a property of matter that determines how it interacts with electromagnetic fields, while electric current is the flow of electric charge through a conductor. In other words, electric charge is the source of electric current, which is the movement of charged particles.
What subatomic particle is most directly related to current electricity?
Electrons are mostdirectlyrelated to electric current. (Electric current is caused by the movement of electrons between atoms.)
