= lilwyne, no problemo..

hurmm...another quest is..how do we know which fuse can we use..? nov/04..34

it says the hair dryer takes 2amps, and the lead can carry 5amps
so it cant be blow 2amps cuz  then the fuse would blow and hair dryer wont work, and it cant be above 5amps, cuz the hairdryer might get messed up
so it has to be between 2-5, and thonly answer there which is between 2-5 is 3amp fuse

oowhh...great..
+rep to eddie and lilwayne..
 ;D..
why i got -rep?..
sory if i did something wrong

statement : a ray parallel to the princilpe line will always refract and pass through the focus..

here the line at the top passes parallel and refracts and meets at 10cm (from the optical center)

therefore it is 10cm - "B"

In A it is connected in parallel..it won't change the p.d. The lamp will get the mains supply. Whereas in B the resistor is a potential divider and can vary the voltage . I hope uve understood
