Q1: Reverse bias is a condition that essentially ___________ current through the diode.A
allows
B
prevents
C
increases
D
blocks
ANS:B - prevents Reverse bias is a condition that essentially increases current through the diode ie, LED are always operated in forward bias, as for high input impedance, as low current flows through the conductor. If it was reverse bias high current flows which ultimately damage/burnt the diode. |
