my txt bk says dat capacitor will nt wrk wid dc n will wrk wid ac
<Cambridge IGCSE Physics- Tom DUncun   pg 196 :P :P :P :P lol>
I checked it out. What is actually means is that current FLOWS thru the circuit with ac and capacitors, not whether it charges or discharges
dc charges it, that's y it blocks the current, as it's gettin charged.
At least that's what I understood. :P The case is open for argument :P  ;D

Heyy..I'm confused with the whole plotting compass thing...
C in a compass, is the needle a magnet, or is like a soft magnet, gets temporarily magnetized wen it's in a field?

N the plotting compass, does it point at the north pole, or north to south? :S
Would appreciate it if someone wud clarify :)

The plotting compass points in the direction of the field lines.
Field lines flow from North to South.
The compass points from the North TO the south.
i.e it points in the direction of the field lines.
TOWARDS south, from NORTH.
That's what the MCQs indicate.
