Chapter 19: Q6CQ (page 694)

Discuss how potential difference and electric field strength are related. Give an example.

Short Answer

Expert verified

The electric field strength is a measure of potential gradient at any point in the field \(\Delta V = E \times d\)

Step by step solution

01

Definition of potential difference and electric field strength

The potential difference between two points in a circuit is the difference in the amount of energy that a unit positive test charge has experienced in moving from one point to another.

The electric field strength is the force experienced by the test charge at a point inside the electric field.

02

Explaining the relationship between potential difference and electric field strength.

If an electric field of magnitude\(E\)is applied, the potential difference between two points separated by a distance\(d\)is given as:

\(\Delta V = E \times d\)

The rate of change of the electrical potential with respect to position is measured by the electric field strength.

What is the strength of the electric field in a region where the electric potential is constant?

A \({\bf{0}}.{\bf{500}}{\rm{ }}{\bf{cm}}\) diameter plastic sphere, used in a static electricity demonstration, has a uniformly distributed \({\bf{40}}.{\bf{0}}{\rm{ }}{\bf{pC}}\)charge on its surface. What is the potential near its surface?

The temperature near the centre of the Sun is thought to be \(15{\rm{ }}million\) degrees Celsius \(\left( {1.5 \times {{10}^7}^o{\rm{ }}C} \right)\). Through what voltage must a singly charged ion be accelerated to have the same energy as the average kinetic energy of ions at this temperature?

Will a negative charge, initially at rest, move toward higher or lower potential? Explain why.

How does the energy contained in a charged capacitor change when a dielectric is inserted, assuming the capacitor is isolated and its charge is constant? Does this imply that work was done?
