The effective value of the maximum voltage of AC voltage is
Amplitude Um
maximum voltage
The voltage increases
Ueff=Um/√2
All of the above choices
Umax =15v.
F=50 Hz
T =0.02sec ,Um =311.2 V.
If the amplitude of AC voltage increases, then:
Amplitude Um
maximum voltage
The voltage increases
Ueff=Um/√2
All of the above choices
Umax =15v.
F=50 Hz
T =0.02sec ,Um =311.2 V.
The amplitude of the voltage means
Amplitude Um
maximum voltage
The voltage increases
Ueff=Um/√2
All of the above choices
Umax =15v.
F=50 Hz
T =0.02sec ,Um =311.2 V.
The wave form in AC voltage is periodic because:
Amplitude Um
maximum voltage
The voltage increases
Ueff=Um/√2
All of the above choices
Umax =15v.
F=50 Hz
T =0.02sec ,Um =311.2 V.
If the period of AC voltage is 20ms, then the frequency is:
Amplitude Um
maximum voltage
The voltage increases
Ueff=Um/√2
All of the above choices
Umax =15v.
F=50 Hz
T =0.02sec ,Um =311.2 V.
In Lebanon, the effective voltage is 220V and frequency is 50Hz so the period and the maximum voltage are:
Amplitude Um
maximum voltage
The voltage increases
Ueff=Um/√2
All of the above choices
Umax =15v.
F=50 Hz
T =0.02sec ,Um =311.2 V.
AC voltage characterized by
Amplitude Um
maximum voltage
The voltage increases
Ueff=Um/√2
All of the above choices
Umax =15v.
F=50 Hz
T =0.02sec ,Um =311.2 V.
If the maximum amplitude(Y) is 3 div, and the vertical sensitivity(Sv) is 5v/div. Then the maximum voltage is
Amplitude Um
maximum voltage
The voltage increases
Ueff=Um/√2
All of the above choices
Umax =15v.
F=50 Hz
T =0.02sec ,Um =311.2 V.
