Figure 8.4.1 : A simple RC circuit. The key to the analysis is to remember that capacitor voltage cannot change instantaneously. Assuming the capacitor is uncharged, the instant power is applied, the capacitor voltage must be zero. Therefore all of the source voltage drops across the resistor. This creates the initial current, and this current

The experiment used single and double capacitor circuits to measure current over time. Graphs of the data were used to calculate the time constants and capacitances. The time constant for the single capacitor was determined to be -3.279 s and the capacitance was calculated to be -3.279 x 10-4 F.
It is a character of the circuit, which is only determined by the resistance in the circuit and the capacitance of the capacitor in a RC circuit. In this experiment, an oscilloscope, a signal generator, several resistors and a capacitor were used to find the relationship between resistance, capacitance and time constant in a RC series circuit.
The time constant is given by the relation: Ļ=RC where R=Resistanceāohms (Ī©)ā§C=Capacitanceāfarads (F) Also, the voltage (V) at any time (t) across the capacitor depends on the final voltage (V 0 ) value across the capacitor following the following formula: But, at half-life time, the value of the capacitor voltage is half the final voltage.
For the double capacitor, the time constant was -6.135 s and the capacitance was -6.135 x 10-4 F. The objectives of determining time constants and capacitances were achieved through quantitative analysis of experimental data.
The first capacitor was called Leyden Jar, which was invented by Ewald Jurgen von Kleist in 1745 and produced by Pieter van Musschenbroek in 1746. The Leyden jar was not a complex device. (See Fig) Its main body is a glass jar lined in and out with metal film. The glass acted as the dielectric. There was half filled water inside the jar.
Generally, the following exponential increasing curve is obtained: The curve also has two regions i. transient period (when it is charging) and steady state period depending whether the capacitor is fully charged. It is observed that the capacitor takes a given time to reach 63% of its final voltage value.
