Hi Everyone,
I am trying to understand the theory of diodes and have following question on basic diode theory, which is really confusing me.
If you had a DC circuit with 3 x standard diodes (0.7v drop) say current rating 20mA, with a 5v source what would be the current flow and power for this circuit?
How would I then calculate the resistance required to make up the rest of the 5v source and would what would be the final power for circuit?
Appreciate the help, I am just getting very confused on diodes and calculating power as most examples show diodes with resistors.
Thanks in advance.
Cheers,
Karv
