LAB 4. Capacitors

Introduction

Any pair of conductors divided by an insulator is a capacitor. If a potential difference V

between the conductor charges is established, +q and -q are visible on the conductors. The

formula for the relationship between q and V is q=VC, where the capacitance of the Capacitor,

expressed in farads F (1F=1C/V), is the constant C. In an RC (resistor-capacitor) circuit, this

experiment explores how capacitors behave while being discharged. Our objective is to

comprehend the basic idea of electrical engineering capacitors discharge stored energy when

connected to a resistor.

In the lab, we first constructed a parallel plate capacitor before looking into capacitor

combinations and the charging and discharging properties of capacitors. Two flat conducting

plates are stacked on top of one another to form a parallel plate capacitor, but they are separated

from one another by an insulating layer. The formula for a parallel plate capacitor’s capacitance

is

C= kx4A

d

Where A is the area of either plate, d is the distance between the plates, k4 is the

permittivity of free space, and k is the insulator’s dielectric constant.

We will construct an RC circuit using a capacitor, resistor, and battery to study the

charging and discharging characteristics of a capacitor. We will connect a charged capacitor to

the resistor and monitor the charge flowing from one of t …
