Electronics help in diode and resistor concept plz?
Q1)what is the difference in the diode of difirent makes?(ofcourse the modle number and the company making it but is there a differnce of the drop(0.7) if all the diodes are of silicon but different model numbers??
i.e. is the a difference in the drop of lN4001 AND lN4007?
Q2)How to measure the drop of the diode by the help of a anologue voltmeter?? (i.e in digital multimeter if we just connect the terminals of the meter to the diode it shows a drop??)
Q2) resistors are used to limit the flow of current but do they have any influence over voltage?? (consider like a 1.5V battery connected in series with a resistor connected in series to a smallll load (LED) )?
Q3) what tolerance is indicated by the golden color 5% or 10%
Theses r a kind of stupid questions but plz request serious and helful answer thanku
silicon diodes are mostly the same,
diode drop about .7 volts
1n4001 to 1n4007 have different reverse peak voltages , like 50 volts to 200 volts
if current flows through a diode, you can measure the voltage with analog meter. put the lead across the diode, measure .7 volts. battery, res, diode, led. in series, use meter. Vbat= Vdiode +Vres+Vled
Q2B, V=IR... voltage drop across the res is current X resistantance
Q3, gold = 5%
