The difference between electric potential and electric field..
Answer to Problem 1QAP
The electric potential is defined as the electric potential energy per unit charge while the electric field is defined as the electric force per unit charge.
Explanation of Solution
Electric potential and electric field are the two different terms use in electrical. The electric potential is defined as the electric potential energy per unit charge. In other words, electric potential is the required work to move a charge from infinite to a point in an electric field.
The expression for the electric potential is given as,
However, the electric field is defined as the electric force per unit charge. The direction of electric field is always taken in the direction of force exerted on the positive test charge.
The expression for the electric field is given as,
Conclusion:
Thus, electric potential is defined as the electric potential energy per unit charge while the electric field is defined as the electric force per unit charge.

- Lab-Based Section Use the following information to answer the lab based scenario. A student performed an experiment in an attempt to determine the index of refraction of glass. The student used a laser and a protractor to measure a variety of angles of incidence and refraction through a semi-circular glass prism. The design of the experiment and the student's results are shown below. Angle of Incidence (°) Angle of Refraction (º) 20 11 30 19 40 26 50 31 60 36 70 38 2a) By hand (i.e., without using computer software), create a linear graph on graph paper using the student's data.
