Circuits

Question 1

Describe and explain the properties of conductors and insulators

Answer 1

Electrical conductivity is the ability of electrons to move in a substance. Substances that allow electrons to move easily are called conductors. Conductors contain atoms in which electrons (-) can move freely. Substances in which it is difficult for electrons to move are insulators. Insulators contain atoms that hold on to their electrons tightly.

Question 2

Describe the differences between series and parallel circuits and identify the type of circuit from a diagram

Answer 2

Parallel Circuit - A circuit that has more than one path for electricity to flow through. If one of the paths has a break in it, the others will still work.
Series Circuit - A circuit with the components joined one after the other in a single continuous loop

Question 3

What advantages does series circuits have over parallel circuit?

Answer 3

Uses less power, easy to build

Question 4

What advantages does parallel circuits have over series circuit?

Answer 4

If one loop is disconnected or broken, then the other remains powered.

Question 5

Which type of circuit gives the brightest bulbs?

Answer 5

Parallel circuit

Question 6

Which type of circuit gives the dimmest bulbs?

Answer 6

Series circuit
