Ohm’s Law – Relationship Between Current and Potential Difference

Relationship Between Current and Potential Difference Ohm’s Law The relationship between the current passing through 2 points in a conductor and the potential difference between the 2 points is given by Ohm’s law. Ohm’s Law states that the current flowing in the metallic conductor is directly proportional to the potential difference applied across it’s ends, … Read more

Current

Current An electric current I is a measure of the rate of flow of electric charge Q through a given cross-section of a conductor. In other words, current is the measure of how fast the charge flow through a cross-section of a conductor. Equation Direction of Current Conventionally, the direction of the electric current is … Read more

Electric Field

Electric Field An electric field is a region in which an electric charged particle experiences an electric force. Electric field is represented by a number of lines with arrows, called electric lines of force or electric field lines. The direction of the field at a point is defined by the direction of the electric force … Read more

Electric Charge

Electric Charge There are two kinds of electric charge, namely the positive charge and the negative charge. Like charge repel each other. Unlike charge attract each other. A neutral body can be attracted by another body which has either a positive or negative charge. The SI unit of electric charge is Coulomb (C).ExampleCharge of 1 … Read more
