Front

What is the principle of superposition in electric fields?

Back

The principle of superposition states that the total electric field created by multiple charges is the vector sum of the electric fields created by each charge individually.

What is the difference between alternating current (AC) and direct current (DC)?

Back

Alternating current (AC) changes direction periodically, while direct current (DC) flows in one direction only.
