Malak:
Can anyone explain The sliding contact thing...Like placing it in which position increases/decreases resistance bla bla...
Thx alot :D
SEL123:
Can someone PLEASE help me with may june 06 PAPER 6 PHYSICS igcse
QUestion 3
V- "Extend the straight line EF within the outline of the block to a point I. The distance FI must be exactly equal to b"
Whaaaaaaaaaaat?
b = FH
H --> p3 and p4 extended to the block
if you can explain the rest of the questions on this page I'd really appreciate it
How can FH and FI be equal
I don't get it
I attached it here

The sliding contact for a variable resistor??
Okay..look
So if the current is coming from the left (conventional current)
If you slide the contact to the left, the resistance decreases---> current increases
If you slide it to the right, the resistance increases
Just imagine it as the resistor getting bigger

Gimme 2mins .. :)
