The waveform of sinusoidal voltage, its frequency and phase can be found by:
Correct answer: A. CRO (Cathode Ray Oscilloscope)
- A. CRO (Cathode Ray Oscilloscope)
- B. Diode
- C. Transistor
- D. Radio
Explanation
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.

About AC Through Resistor, Capacitor and Inductor
Alternating current through a resistor, capacitor and inductor involves phase relationships between voltage and current, reactance, impedance and energy transfer. A resistor keeps voltage and current in phase, while a capacitor and inductor produce opposite phase shifts, a distinction used in circuit diagrams and numerical calculations.
