Relation between Electric Field and Electric Potential.Who gave the concept of electric field lines?Īns: Michael Faraday gave the concept of electric field lines.Īns: Electric field lines are a pictorial representation of the electric field around a charge or system of charges. What is the conventional direction of the electric field?Īns: Electric field lines start from the positive charge and end at the negative charge. What information is conveyed from the map of electric field lines about electric fields?Īns: Electric field lines provide information about the strength and direction of the electric field. What is another name for electric field lines?Īns: Electric field lines are also called lines of electric force. Electric field lines are a visual portrayal of electric field around a charge or system of charges.
It should be noted that electric field is proportional to the electric field lines per unit area if the they emerge uniformly from the charge. Images Coming soon Electric Field Lines Due to Some Charge ConfigurationsĮlectric field lines for a combination of two positive or negative charges:įor a system of two positive charges, the field lines show the repulsion between them.Įlectric field lines for a combination of one positive and one negative charge: And for non-uniform electric field, the field lines will not be parallel. If the electric field lines are straight, at an equidistant from each other or if they are parallel, then the electric field is uniform. In a given region if the electric field is zero, then electric field lines do not exist. $$\mathrm$.Įlectric field lines never pass through a conductor means that the electric field inside a conductor is always zero. If we bring a test charge at any point in the region of electric field of the source charge Q, then the test charge will experience a force. We define the electric field as the region or space around a charge within which if we place another charge, then it will experience an electric force on it which can be attractive or repulsive depending on the polarity of the source and the test charge. The gravitational field is created due to the masses present but the electric field is created due to charges and the time-varying magnetic fields. We know that in the gravitational field an object creates gravitation around it and if any other object is placed inside that region, it will experience a gravitational force.
