GUYS HELP 4 PHYSICS PAPER 3

[Mohammed Khalaf]

Good luck to everyone, I have the exam in 1 hour

All da best do well
if u finish fast come online nd tell us hw did it go before we enter ours

That's all actually,and you have to know it used for time delay circuits.

 

[Yousif Mukkhtar]

Time delay circuits are circuits having a lamp which switches on after some time. That is because a capacitor is used which is charging up; i.e storing electrical energy. After sometime the energy is high enough for a lamp to switch after some particular time.

Its a bit complicated, its just for confusing candidates (CIE is so selfish.. )

thankkuuu

thankkuuu

you can take it in this way
R proportional to 1/A
area of wire is pie r*sq*
you half the radius the area becomes 1/4
so resistance increased by 4 times
16 ohms
