Answer 4

but i need my space :P

Answer 5

Please do not underestimate any questions :|
The potential of two plates of a capacitor are +10V and -10V.The charge on one of the plates is 40C.The capacitance of the capacitor is?
A)2F B)4F C) 0.5F D)0.25 F

Answer 6

I am getting 4F

Answer 7

ok.. how is it 4?

the potential difference is 20V.. charge is 40C.. C=q/V => 40/20 = 2F

Answer 8

:O i see okay i thought PD =10
silly me

Answer 9
