Is the increase in voltage causes a greater electric resistance in a circuit?

No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.


4 most important factors in an electric circuit?

electromotive force, current, resistance, and power


What would happen to circuit if there was no resistance?

a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()


What determines the amount of electric current flow through a circuit?

voltage and resistance v=ir v=voltage i=current r=resistance in physics right now


Application of electrical circuit analogies in magnetic circuit?

Magnetic circuit follows equation (4) that is Ni = (Ф) ( l / μA) or m.m.f(magneto motive force) = (Flux) (reluctance).Electric circuit follows ohm's law that is E = I.R or e.m.f(electro motive force) = (current) (Resistance)From above point m.m.f in magnetic circuit is like as e.m.f in electrical circuit.Flux in magnetic circuit is similar as current in electrical circuit.Reluctance in magnetic circuit, S = ( l / μA) is similar to resistance R = (ρl/A) in electric circuit.Permeance (= 1/reluctance) in magnetic circuit is equivalent to conductance (=1/resistance) in electric circuit.In magnetic circuit flux establishes but not flow like as current in magnetic circuit.In magnetic circuit energy needed only to establish the flux but no consistent energy need to maintain it whereas in electric circuit continuous energy needed to flow of current.Resistance of an electric circuit is constant (for same temperature) and is independent of current but reluctance of magnetic circuit is not constant because it depends on μ (=B/H) which is not constant and depends on B/H.

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 does a variable resistor do and how does it affect the flow of electric current in a circuit?

A variable resistor is a component that can change its resistance value. By adjusting the resistance, it can control the flow of electric current in a circuit. Increasing the resistance reduces the current flow, while decreasing the resistance increases the current flow. This allows for precise control of the current in a circuit.
