ECEN 3714 Lecture 2: Chapter 4 Terms

Which of the following would double the amount of current flowing through a piece of the metal rod? 

1. Halve the voltage across it

2. Double the voltage across it. 

3. Quarter the resistance across it. 

4. Quadruple the voltage across it.

Consider the full-wave rectifier circuit as shown below with C = 474 F and transformer winding ratio of 14:1. If the input voltage is 120 VAC (RMS) at 60 Hz, what is the load resistor value for a peak-to-peak ripple less than 0.5 V? What is the output DC voltage? Assume ideal diode.

A amplifier circuit with a voltage gain 100 gives 2 volt output what would be the input
