Where do you expect the strongest electric field?
The direction of the field line at a point is the direction of the field at that point. The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest.
What does a field diagram show?
An array of field lines is called a field line diagram, and it is a way of representing both the direction and the strength of a vector field. The direction is found by focusing on an individual field line, as above. The strength is found by looking at the density of field lines.
Can electric field lines cross superposition?
The second property tells you that the field lines can never cross. The principle of superposition tells us that the net field is simply the vector sum of the two. So the total field would only have one line going through the same point with a direction which was given by the sum of the two other directions.
What is the magnitude and direction of the electric field?
The magnitude of the electric field produced by charge A at point P. Charge A is positive so that the direction of the electric field points away from charge A (to the right).
What is meant by saying charge is conserved?
Term. Meaning. Law of conservation of charge. Charge is neither created nor destroyed, it can only be transferred from one system to another.
How are charges conserved?
In particle physics, charge conservation means that in reactions that create charged particles, equal numbers of positive and negative particles are always created, keeping the net amount of charge unchanged. Similarly, when particles are destroyed, equal numbers of positive and negative charges are destroyed.
What do you mean by conservation of charge give at least two examples of it?
For example, 1) Due to friction opposite charges appear on two bodies that are rubbing against each other bu the net charge is still zero. 2) During radioactive decay, a proton decays into a positron and a neutron, again no net charge production. Answer verified by Toppr. Upvote (0)
Why is current conserved at a junction?
Components that are connected on separate loops are connected in parallel. The current is shared between each component connected in parallel. The total amount of current flowing into the junction, or split, is equal to the total current flowing out. The current is described as being conserved.
What is current conservation?
current conservation is a not-for-profit quarterly print and online magazine that works with scientists, science writers, and artists across the world to tell stories from the field of conservation in a manner that engages both scientific and non-scientific audiences.
What is the most important wildlife problem globally?
Wildlife is suffering Some of the biggest threats to wildlife include illegal wildlife trade, habitat destruction, invasive species, pollution, and clime change. Illegal Wildlife Trade: The illegal wildlife trade is the fourth largest criminal industry in the world, after drugs, arms, and human trafficking.
What happens to the current at a junction?
Current measures the amount of charge that flows in a circuit. Kirchhoff’s Junction Rule says that the current going into a junction must equal the current coming out. In parallel circuits, junctions cause the current to branch, but the junction rule can be used to determine how the current is distributed.
