alternating current

Question 1

alternating current

Answer 1

a current that changes direction periodically and whose magnitude varies continuously with time

Question 2

rectification

Answer 2

process of converting alternating current into direct current

Question 3

types of rectification

Answer 3

1. half-wave rectification
2. full-wave rectification

Question 4

half-wave rectification during positive half-cycle

Answer 4

• diode is forward biased
• current flows through the load

Question 5

half-wave rectification during negative half-cycle

Answer 5

• diode is reverse biased
• no current flows

Question 6

smoothing using capacitor

Answer 6

• capacitor is connected in parallel with the load resistor

Question 7

effect of capacitance and load resistance

Answer 7

larger capacitance results in smoother output and steadier DC than small capacitance
