How is an electric current produced and what factors influence its generation?
An electric current is produced when electrons flow through a conductor, such as a wire. Factors that influence the generation of an electric current include the voltage applied, the resistance of the conductor, and the presence of a closed circuit.
On what factors does the amount of heat produced in an electric wire depend?
The amount of heat produced in an electric wire depends on its resistance, the current flowing through it, and the duration for which the current flows. The formula for calculating heat generated in a wire is H = I^2 * R * t, where H is the heat produced, I is the current, R is the resistance, and t is the time.
What does a magnet have to do to produce an electric current?
To produce an electric current, a magnet must move relative to a conductor, such as a wire. This movement induces a changing magnetic field around the conductor, which in turn generates an electric current through the process of electromagnetic induction. The strength of the current produced depends on factors like the speed of movement and the strength of the magnetic field.
What is resistivity on what factor is depends?
Resistivity is a measure of a material's ability to resist the flow of electric current. It depends on factors such as the material's composition, temperature, and dimensions. Materials with high resistivity impede the flow of current more than those with low resistivity.
On what factors does the strength of an electroment depends?
The strength of electromagnet depends on the electric current flowing through the core because when the current is stopped, the core is no longer magnetized and the rate of change of flux linkage.
What are the factors on which the heat produced the electric current depends upon?
It depends on1 the resistance of wire.2the voltage between the ends of the wire.3the flowing current time.

How does fire influence the factors of production?
It depends what is being produced.
What is the process by which electric current is generated by a wire a magnetic field?
When a wire moves through a magnetic field, it experiences a force that pushes free electrons along the wire, creating an electric current. This phenomenon is known as electromagnetic induction and is the basic principle behind how electric generators work. The strength of the current generated depends on factors such as the rate of motion of the wire and the strength of the magnetic field.
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
High voltage by itself does not produce electric shock What does?
Electric shock occurs when high voltage passes through a person's body, typically when they provide a path for the electrical current to flow, such as through their hand or foot. The severity of the shock depends on factors such as the amount of current and the path it takes through the body.
On what factors the current flowing through a device depends?
Current flowing through a device depends on resistance offered by that device.
Which factors affect the magnetic strength of a solenoid which is carrying an electric current?
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
