Answer :
8.2 X [tex]10^{5}[/tex]C quantity of charge is supplied by the battery to charge the capacitors.
[tex]C_{net } = \frac{C_{1} C_{2} }{C_{1} +C_{2} }[/tex]
= [tex]\frac{3\times 4}{3+4}[/tex]
= 12/17
= 1.714μ F
Q = CV
= 1.714x [tex]10^{6}[/tex] F X 48V
= 82.27x [tex]10^{6}[/tex]C
= 8.2 X [tex]10^{5}[/tex]C
What is capacitor?
A two-terminal electrical device known as a capacitor is capable of storing energy in the form of an electric charge. It is made up of two electrical wires that are spaced apart by a certain amount. Suction may be used to fill the space between the conductors, or a dielectric, an insulating substance, may be used instead. Capacitance is the term used to describe a capacitor's capacity to hold charges.
Pairs of opposing charges are held apart in capacitors to retain energy. A parallel plate capacitor has the most basic construction and is made up of two metal plates with a space in between them. However, many capacitor types are produced in a wide variety of shapes, sizes, lengths, girths, and materials.
