a 3.0-pf capacitor is connected in series with a 4.0-f capacitor and a 48-v battery. what quantity of charge is supplied by the battery to charge the capacitors?



Answer :

PNaik

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.
