What sentence(s) is/are true when we talk about equipotential lines?

Physics
1 answer:
rodikova [14]3 years ago
6 0

Answer:

a. True

Explanation:

Equipotential lines are the imaginary lines in the space where actually the electric potential is same at each and every point.

Work is not required to move along such points of the equipotential line because the movement is always perpendicular to the electric field lines because these lines are always perpendicular to the electric field lines.

The electric potential for a point charge is given mathematically as:

V=\frac{1}{4\pi.\epsilon_0}\times \frac{Q}{r}

where:

Q= magnitude of the point charge

r= radial distance form the charge

\epsilon_0= permittivity of free space

Describe the difference between a conductor and an insulator in terms of thermal energy transfer and provide an example of each.
Nikitich [7]

The difference between conductors and insulators is because of electronic structure of atoms and molecules.

 

Anywhere we have free electrons, we have a hard conductor where free electrons help in conduction.

 

In electrolytes, charged Ions do conduction.

 

Dielectrics (or insulators) don't have free electrons current.

 

Free electrons mean, the electrons that are not related with a specific atom, they are allowed to move nearby the crystal lattice.

When does a lightbulb carry more current, (a) immediately after it is turned on and the glow of the metal filament is increasing
emmasim [6.3K]

A  lightbulb carries more current immediately after it is turned on and the glow of the metal filament is increasing; option A.

<h3>What is current?</h3>

Current refers to the flow of electric charges typically electrons.

Current flowing through a metallic material decreases with increase in temperature of the material.

This is because the resistance of the metal increases with increase in temperature.

Therefore, for a light bulb, the current flow through it will be maximum when it is just turned on because the temperature, and hence the resistance of the  filament is at its lowest.

In conclusion, current flow decreases with increase in resistance.
