1
Q
What is the symbol w represtent
A
Waveform over time which is measured in radians per second.
2
Q
What is the formula for period
A
T = 1 / frequency
3
Q
What does rhe small v represent
A
Small v is for instantaneous voltage (AC)
4
Q
How to calculate power in an AC circuit
A
Power = Vrms x Irms
5
Q
What is form factor?
A
The ratio between rms value to average value.
=Vrms / Vave. So 0.707/0.637 = 1.1107
6
Q
Give the angle in degrees and radians for: 1 cycle, 1/2 cycle, 1/4 and 3/4
A
2pie - 360
Pie - 180
2pie/4 - 90
3 x pie/4. - 270
7
Q
What are the square wave calculations?
A
Peak value is V Peak to peak is 2V Average value is V/2 rms value is V/2 Power factor is V x I / 4 or 0.25
