Alternating Current
ROOT MEAN SQUARE
MEAN OR AVERAGE CURRENT
- the average /mean value of a current in a half-cycle flows a current
-
ROOT MEAN SQUARE CURRENT
- Is defined as the value of the steady DC which produces the same power in resistor as the mean(average) power produced by the AC
-
ROOT MEAN SQUARE VOLTAGE
- The value of the steady direct voltage which when applied across a resistor produce the same power as the mean(average) power produced by the alternating voltage across the same resistor
-
Alternating Current
- an electric current whose magnitude and direction change periodic ally.
Sinusoidal Alternating Voltage
- AC flows through a resistor there will be a potential difference (voltage) across it and this voltage is alternating
Terminology in AC
PERIOD
- A time taken for one complete cycle
- Unit: second(s)
PEAK CURRENT
- A magnitude of the maximum current
- Unit:Ampere(A)
FREQUENCY
- A number of a complete cycle in one second
- Unit: hertz(Hz)/s-1
