Answer:
a) the greatest charge will be on C3=3 mF
b) Voltage will be same across each capacitors
Explanation:
Given: C1 = 1 mF, C2 =2 mF, C3 = 3 mf and V= 9 volts
To Find: greatest charge Q=? and which capacitor has the greatest voltage=?
Solution:
a)
As the voltage across each will be same so (using Q = C V)
Q1 = 1 mF × V
Q2 = 2 mF × V
Q3 = 3 mF × V
so the greatest charge will be on C3=3 mF
b) Voltage will be same across each capacitors
Answer:
a) the 3mf capacitor has the greatest charge.
b) they all have equal voltage which is 9V
Explanation:
a) the charge on a capacitor is the product of the capacitance and the voltage across the capacitor. It can be written as;
Q = CV
And since they are connected in parallel, the voltage across each capacitor will be the same and equal to 9V
V1 = V2 = V3 = 9V
So,
For capacitors
Q1 = 1mF × 9V = 9mC
Q2 = 2mF × 9V = 18mC
Q3 = 3mF × 9V = 27mC
Therefore, the 3mF capacitor have the highest charge.
b) Since it is a parallel connection, the voltage across each capacitor is the same and equal to 9V.
