u help me loads kiddo!!

btw i knw hindi like 70% only :3

When are your exams ?

70% Sachi ?

Qu 7(b)

for c(i) should it start at zero or above?

7b)
• The Voltage is fixed since it is determined by the rate of change of flux.
• Higher resistance, means less Induced Current since R=V/I.
• Less induced current means less energy loss by motor effect, therefore less damping. P = V x I or P = V^2 / r but you cant use P = I^2 R since the current changes x2!
--- > If you do this in an open circuit. Resistance is maximum , current is zero, so no damping.

ci)
Above, not zero :¬

Help me out with this :/

 

[♣♠ Magnanimous ♣♠]

Help me out with this :/

i think it may be B or A

 

[RoOkaYya G]

Help me out with this :/

it should be C coz since the bulbs r in parallel it doesnt affect the circuit.
same current passes through ammeter


cross check with someone else.

Lol, I posted wrong question, this is easy Well I solved another as well Thanks though, and yes answer is C. LOL so easy

yea i saw it.i meant im still sane coz it was right ^_^

btw u shldve drawn the graph on fig 7.2....thts wht im actually confused abt -_-

You said for c question. Dont lie.
for 7.2 clue,
• The Voltage is fixed since it is determined by the rate of change of flux.
• Higher resistance, means less Induced Current since R=V/I.
• Less induced current means less energy loss by motor effect, therefore less damping. P = V x I or P = V^2 / r but you cant use P = I^2 R since the current changes x2!

i was correct abt the dumb question i meant -_-...the ammeter one -_-

i was correct abt the dumb question i meant -_-...the ammeter one -_-

Which Ammeter one ? . _ . 7.2 isn't ammeter one . _ . :/
Do you need hand written notes on A2 level physics ?

whn i said i was right i meant for the ammeter one (ur quest)

then i replied for my question sayin tht i need the graph drawn only for 7(b)

ok send me!! ^_^
