What opposing force must be overcome by charge flowing electric current?
Resistance
What opposing force must be overcome by charges blowing in electric current?
Resistance is the opposing force that must be overcome by charges blowing in an electric current. Resistance is caused by factors like the material of the conductive medium, its temperature, and the dimensions of the conductor.
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 will an electric current follow?
An electric current follows the path of least resistance.
What is the role of resistance in an electric circuit and how does it affect the flow of current?
Resistance in an electric circuit is the opposition to the flow of electric current. It is measured in ohms. Resistance affects the flow of current by reducing it, as higher resistance leads to lower current flow. This relationship is described by Ohm's Law, which states that current is inversely proportional to resistance in a circuit.
What is joule's law of heating?
The heat produced due to electric current through a resistance is i) directly proportional to the square of the current ii) directly proportional to the resistance value of the conductor iii) directly proportional to the time of flow of current.
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.
What is the term used for the hindrance a conductor creates to the flow of electric current?
Resistance is the hindrance a conductor creates to the flow of electric current
