Answer 2

Hello

"resistance is a property of wire to resist the flow of electrons."

it is needed so that :-

• we can be provided with our desired vAlue of current.
• to block unnecessary current.
• some devices , resistance is only used . example bulb.
• to protect ur devices from excessive current.

(any wire will always have resistance)

(we can only reduce never )

i hope u got the answer

Have a nice day ahead.
