Question

a diode used in a circuit has any constant voltage drop of 0.5 volt all current and maximum power rating of 100 MW find the value of the resistance are connected in series with the diode for obtaining Maximum current​

Answer 1

Answer:

5 ohm

Explantation:

$power = vicos \\ so \\ \cos = (1) \\ p = vi \\ 100 \times {10}^{ - 3 } = 0.5 \times i \\ i = 0.2amp \\ voltage \: = 1.5 - 0.5 = 1v \\ r = \frac{v }{i} = \frac{1}{0.2} = 5 \\ r \: = 5ohm$
