Question

insulators and conductors (worksheet)
q.1. fill in the blanks with suitable words.
a)
materials such as steel that electric current flow through them easily are called ____________.
b)
materials such as wood that electric current cannot flow through them easily are called ____________.
q.2. write t or true if the statement is true; write f or false if the statement is false.
______ 1. all conductors conduct electricity equally well.
______ 2. insulators are important to protect us from getting electrocuted.
______ 3. electrons can move easily in metals so metals are usually good insulators.

Explanation:

Q.1

a)

In the context of electricity, materials that allow electric current to flow through them easily are defined as conductors. Steel is a metal, and metals are good conductors of electricity, so the word to fill in is "conductors".

Materials that do not allow electric current to flow through them easily are known as insulators. Wood is a material that resists the flow of electric current, so the appropriate word here is "insulators".

Different conductors have different levels of conductivity. For example, silver is a better conductor than copper, and copper is better than steel. So not all conductors conduct electricity equally well, making the statement false.

Answer:

conductors

b)
