The selected answer is wrong:
FROM D QUESTION I WAS MADE TO UNDERSTAND AM TO LOOK FOR THE QUANTITY WHICH I DID USING
Q=CV
=1*0.1
=1
I WISH FOR MYSCHOOL TO ADD THE MARK WHICH IT DEDUCTED WHICH I GOT
REF: CHECK NEW SCHOOL PHYSICS
The selected answer is wrong:
Q = CV = 0.1 x 10 = 1C
therefore the correct option is A
REF: i have none now
Ok...the formula used here is the formula for workdone. The correct formula is C=Q/v I.e Q=CV
Q=10x0.1=1C
energy stored in a capacitor is ½cv²... while the chare(Q) in a capacitor is cv (i.e Q=CV)... from d question C=0.1F and V= 10v.
therefore Q=0.1 * 10
Q=1C
Q= CV=1C the solution given is wrong because it solves for energy stored and not quantity of charge
Thanks for your contributions. If you feel the answer is wrong, give a detailed explanation to back your answer.
Thanks for your contributions. Please give a detailed explanation to back up your answer.
Note..we whre ask what charge is store in other words is talking abt the energy store.i think the ans is 5C.what the you think my fellow gr8 Nigeria student?
