What is the definition of resistance in physics?
What is the definition of resistance in physics? What is Resistance of a Conductor The movement of electron gives rise to the flow of current through metals. The moving electrons collide with each other as well as with the positive ions present in the metallic conductor. These collisions tend to slow down the speed of the electrons and hence oppose the flow of electric … [Read more...] about What is the definition of resistance in physics?
What is Electric Current
What is Electric Current Electric Charge and Electric CurrentWhat is an electric charge? Objects that exert electric forces are said to have electric charges. Electric charge is the source of electrical force.There are two types of electrical charges, positive (+) and negative (-). Two like charges (+ and + or - and -) repel each other. Two unlike … [Read more...] about What is Electric Current
How do you calculate the total resistance of a series circuit?
How do you calculate the total resistance of a series circuit? The Effective Resistance of Resistors Connected in SeriesThere are three important characteristics in a series circuit: (a) The current passing through each resistor is the same. (b) The potential difference across each resistor depends directly on its resistance. (c) The sum of the potential difference … [Read more...] about How do you calculate the total resistance of a series circuit?
What Is Resistivity
What Is Resistivity where ρ (rho) is called resistivity of the material of conductor. If, l = 1 m and a = 1 m2 Then R = ρ .... (ii) Thus, if we take 1 metre long piece of a substance having a cross-sectional area of 1 meter2, then the resistance of that piece of the substance is called its resistivity. Resistivity of a substance can … [Read more...] about What Is Resistivity
