Is it C

thts what i thought but its written A in my book.....the physics matter one.....if u have it can u check the answer for surety....and explain me y is the answer A....

 

[Laibaaa]

What would happen if the options were in the box respectively? :|

wts d ans? B or A???

 

[Laibaaa]

wts d ans? B or A?

Answer is A.
But Im asking what would happen in the box if other options were in it

 

[exploded diper]

not b cuz it contains a cell so the ammeter will always show a current......other two not becuz the coil will be needed to show deflection due to a magnet......

What is a transistor? D: omg why do i not know this

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power.
Advantages of a transistor: Fast, Cheap, Doesn’t wear out; because it has no moving parts.

I came across it earlier today. Now you know what it is, eh. So, no worries
It's definition + advantages.
Logic gates are made from transistors.

'switch electronic signals and electrical power' meaning? :/
Haha, I've done logic gates, didn't come across this tho. Anyway, thank you very much!
