Concepts Of Physics MCQ Edition [Volume 2]PhysicsElectric Current through Gases
A 50 Hz AC source, a diode, and a resistor are wired together in series. What is the number of current pulses per second flowing through the resistor?
Options
- A25
- B100
- C200
- D50
Correct answer
D. 50
Step-by-step solution
The given circuit consists of an AC source, a diode, and a resistor connected in series, which forms a half-wave rectifier. In a half-wave rectifier, the diode is forward-biased and conducts current only during one half of the AC cycle. Thus, for every complete cycle of the AC input, exactly one current pulse flows through the resistor. The frequency of the AC source is given as 50 Hz , which means there are 50 complete cycles per second. Therefore, the number of current pulses per second flowing through the resist
