what is electrical resistance? On what does the resistance of a piece of material depend? How does resistance affect current?
Answers
Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it. The resistance is measured in units of ohms (Ω). If we make an analogy to water flow in pipes, the resistance is bigger when the pipe is thinner, so the water flow is decreased.
it depends on the length of the wire, the cross-sectional area of the wire, and the resistivity of the material composing the wire.
it reduces the flow of current or increases it.
hope my answer helps you. if it does mark as brainliest
Explanation:
The obstruction offered by a conducter to the flow the current is called a Resistance
(a) Resistance of a conductor depends if it Nature. Resistance of a conductor is directly proportional to its length.
(b) Resistance of a conductor is inversely proportional to its aeria of it resistance
