See how to calculate the resistance of a component.
What is resistance in electricity simple.
Is an expression of ohm s law.
Resistance is measured in ohms symbol ω.
Now you should understand the concepts of voltage current resistance and how the three are related.
By knowing this simple law you understand the concept that is the basis for the analysis of any electrical circuit.
The very important equation voltage current x resistance v i x r.
It is the opposition to current and is symbolized by r.
Its unit is the ohm symbolized by the greek letter ω.
What is ohm s law.
The electrical resistance of an electrical conductor is a measure of the difficulty of passing an electric current through a substance.
Resistance is a property that determines how good a material is as an electricity conductor.
Electrical resistance is the hindrance to the flow of charge through an electric circuit.
The bigger the resistance the smaller the current.
Resistance is a measure of how much a component decreases the current see resistor.
The majority of equations and laws for analyzing circuits can be derived directly from ohm s law.
Resistance also known as ohmic resistance or electrical resistance is a measure of the opposition to current flow in an electrical circuit.
Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it.
