Answer:
Explanation:
The capacitor of a parallel-plate capacitor is given by:
where
A is the area of each plate
d is the separation between the plates
is the vacuum permittivity
The energy stored in a capacitor instead is given by
where
Q is the charge stored in each plate
Substituting the expression we found for C inside the last formula,
And re-arranging it
Now if we substitute
We find the charge stored on the capacitor:
Answer
given,
capacitance = C = 3.4-µF
inductance = L = 0.08 H
frequency is expressed as
time period
after time T/4 current reach maximum
t = 8.2 x 10⁻⁴ s
t = 0.82 ms
b) using law of conservation
I = 0.010 A
I = 10 mA
Answer:
Change in Velocity because
Explanation:
Remeber area is length times Width. In this case, the area under a accleraton vs time graph is Accleration Times Time. Which is velocity
