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 met…

What is Electric CurrentElectric 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, pos…

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 pote…

What Is Resistivity \( R\propto l \) \( R\propto \frac{1}{a} \) \( \text{So, }R\propto \frac{\ell }{a} \) \( \text{or }R=\rho \times \frac{\ell }{a}\text{ }………\text{ (i)} \) where ρ (rho) is called resistivity of the material of conductor. If,        l …

How series and parallel circuits are different?Series and Parallel CircuitsElectrical circuit can be connected in two basic ways, in series or in parallel. In a series circuit, all the components are connected one after the other in one single path.Figur…

What is the Ohm’s law?The proportional relationship of the potential difference between the ends of an ideal conductor and the current passing through it is known as Ohm’s law.Ohm’s law states that the current passing through an ideal conductor is direc…

Flow Of Current In A MetalFlow of electric current  Three basic conditions are required for an electric current to flow. A device used to produce an electric current like cell, battery, or a plug point acting as a source. A wire made of a metal like cop…

How do you calculate the total resistance of a parallel circuit?The Effective Resistance of Resistors Connected in ParallelThere are three important characteristics in a parallel circuit: (a) The potential difference is the same across each resistor. (b)…
