Question 121: Semiconductors and Logic Gates

Question

A 5V battery is connected across the points X and Y. Assume D
1
and D
2
to be normal silicon diodes. Find the current supplied by the battery if the +ve terminal of the battery is connected to point X.

Accepted Answer

Since silicon diode is used so 0.7 Volt is drop across it, only D
1
will conduct.
So current through cell,
I = $${{5 - 0.7} \over {10}}$$ = 0.43 A

Answer

$$ \sim $$ 0.5 A

Answer

$$ \sim $$ 1.5 A

Answer

$$ \sim $$ 0.43 A

Answer

$$ \sim $$ 0.86 A
