What is charging by induction?
300
This is why toner is given a positive charge in a laser printer.
What is the positive charge on the toner and the negative charge on the drum, which cause them to stick to each other?
300
This is the reason why we use a circuit diagram to represent the components in a circuit?
What is that using symbols to represent an electric circuit makes it easier to comprehend and more convenient?

These are direct currents and alternating currents.
What are currents that are supplied from an electric cell flows in a single direction, and what are electric currents that periodically reverse their directions?
400
This is being "isolated".
What is the act of holding static charge because it is not in direct contact with its surroundings?
400
This is how you get a spark by touching a doorknob after you have walked across a carpet.

These two relationships are stated in Coulomb's law. (And explain these two relationships)
What is direct relationship, a relationship between two objects that causes the value of an object to increase when the value of the other object increases; and what is inverse relationship, a relationship between two objects that causes the value of an object to decrease when the value of the other object increases?
