Abstract
Alternating current (AC) electricity is the type of electricity that commonly used in houses and businesses throughout the world. While direct current (DC) electricity is flowing in one direction through a wire, the direction of the AC is moving in a back-and-forth motion.
AC electricity is created by an AC electric generator, which is determining the frequency. The special about AC electricity is the voltage can be readily changed, so that will make it more suitable for long-distance transmission than DC electricity. However, AC can employ capacitors and inductors in electronic circuitry that will allow for a wide range of applications.
This experiment was amid to create signals for AC voltage using function generator, measuring the signals using oscilloscope, determining the RMS value of AC signals, analyze the effect of frequency, offset and peak voltage on its value. …show more content…
It is measured in volts, V.
Peak voltage is another name for amplitude.
Peak-peak voltage is twice the peak voltage (amplitude). When reading an oscilloscope trace it is usual to measure peak-peak voltage.
Time period is the time taken for the signal to complete one cycle.
It is measured in seconds (s), but time periods tend to be short so milliseconds (ms) and microseconds (µs) are often used. 1ms = 0.001s and 1µs = 0.000001s.
Frequency is the number of cycles per second.
It is measured in hertz (Hz). frequency = | 1 | | time period | | | | | |
The tables below shows a summary of the theoretical equations for different signals, with and without an offset.
(1) With No DC offset Signal | Equation V(t) = | VRMS | VAVG | Sinusoidal wave | | | ZERO | Square wave | | | ZERO | Triangular wave | | | ZERO |
(2) With DC offset Signal | Equation V(t) = | VRMS | VAVG | Sinusoidal wave | | | | Square wave | | | | Triangular wave | | |
