What is Resistor? Factors which affects Resistance and Characteristics
In this video What is Resistor? Ohm's Law, Factor which affects resistance and Characteristics of Resistor explained with examples. What is Resistor? A resistor is a passive electrical component that opposes the flow of electric current. What is Resistance? The property of an object (Resistor) to oppose the flow of electric current is known as resistance, SI unit of resistance is Ohm (Ω). What is Ohm? Transmitting a current of one ampere when a voltage of one volt is applied across a resistor. What does Ohm's law state? Ohm's law defines that electrical resistance equals to voltage divided by current, The relationship between current, voltage, and resistance is described by Mr.Ohm a german scientist in 1827. What are the factors that affect resistance? Electrical resistance is directly proportional to the nature of the material (Resistivity: measured in Ωm, ohm meter) Resistance is directly proportional to the length (L) of the conductor and inversely proportional to the cross-sectional area (A). It is given by the relation "R = ρL/A", Characteristics of Resistor: These are the different characteristics of resistor which we should consider before selecting a particular resistor for any application, 1)Power rating, 2)Tolerance, 3)Temperature co-efficient, 4)Noise, 5)Frequency response, and 6)Stability. This video is helpful to all the students of engineering and science to understand the concept of the resistor and resistance.
