The waveform of sinusoidal voltage, its frequency and phase can be found by:
- A
CRO (Cathode Ray Oscilloscope)
- B
Diode
- C
Transistor
- D
Radio
The correct answer is CRO (Cathode Ray Oscilloscope). A CRO is designed to visually display the waveform of electrical signals, allowing users to measure and analyze the signal's frequency, amplitude, and phase. It is a versatile tool used in laboratories and for troubleshooting electronic devices. On the other hand, a diode, transistor, and radio serve different purposes and are not capable of displaying or analyzing waveforms.
A CRO is an electronic device used to display and analyze the waveform, frequency, and phase of various electronic signals, including sinusoidal voltages.
A diode is a semiconductor device that allows current to flow in one direction only. It is not used to display waveforms.
A transistor is a semiconductor device used to amplify or switch electronic signals. It does not display waveforms.
A radio is a device that receives and demodulates radio signals to produce sound. It is not used to display waveforms.
