# What is the path of electrons in presence and absence of electric field?

Contents

In the absence of an external electric field, the trajectory of electron will be straight line. And in the presence of an external electric field, the trajectory of an electron will be curved one with acceleration along the field.

## What is the path of electrons in absence of electric field?

i) In the absence of electric field the path of electrons are straight lines between successive collisions. ii) When an electric field is set up from positive to negative charge, the electrons are accelerated towards the negative charge.

## What is the path of electron in presence of electric field?

ii) When an electric field is set up from positive to negative charge, the electrons are accelerated towards the negative charge. Therefore, in the presence of electric field the electrons follow a curved path in between successive collisions.

## What is the path taken by an electron inside a conductor in presence of field?

(a) (i) In the presence of electric field, the paths of free electrons in a metal conductor are curved. (ii) In the absecnce of electice field, the paths of free electrons in a metal conductor are straight lines between two successive collisions.

## What are the possible path of free electron inside a conductor?

(i) Absence of electric field: In the absence of an electric field, the paths of free electrons in a metal conductor are straight lines between two consecutive collisions. (ii) Presence of electric field: In the presence of an electric field, the paths of free electrons in a metal conductor are twisted.

## What is the nature of path of electrons in a absence of field B presence of field?

(1) In the presence of electric field the path of the electron is zig-zag but moving in one direction because of the applied electric field. (2) In the absence of electric field the path of the electron is tally random zig-zag because of the thermal motion of the electron.

## What is the nature of path between two successive collision of electrons in the absence of electric field?

In the absence of an electric field, the paths of electrons between successive collisions are straight lines.

## What is the path of electron in magnetic and electric field?

Motion in magnetic and electric fields

In a magnetic field the force is always at right angles to the motion of the electron (Fleming’s left hand rule) and so the resulting path of the electron is circular (Figure 1).

## What is path followed by electron in parallel electric field?

If a charged particle moves in the direction of electric field, Then it is accelerated and will move in same direction of electric field. But if a charged particle moves in a direction and not in parallel to electric field, it moves in a parabolic path.

## What is the nature of path of an electron when it moves in a transverse electric field?

The particle will move in the curved path and will form a circle. So, when the electron moves in the transverse magnetic field its path becomes circular.

## When no current is passed through a conductor?

When no current is passed through a conductor, the average of the velocities of all the free electrons at an instant is zero.

## What is the shape of the path of a free electron of a metal?

Explanation:The path of motion of free electrons in a metal is zig-zag. The normal motion of “free” electrons in a conductor is random, with no particular direction or speed.

## When a steady electric current flows through a non uniform conductor?

Note: When a steady current flows in a metallic conductor of non-uniform cross-section, the conductor’s current flowing is constant. Current does not depend on the conductor area; it remains constant. Current density, drift speed, and electric field are inversely proportionate to the cross-section area.
