Answer:
4
Explanation:
The reaction between hydrogen and oxygen gives water (H2O)
2H,+O, -> 2H2O
Oxygen is a gas O, = O2
Balancing both sides
let , be x
2x = 4
x= 2
Therefore, 2H2 = 4 hydrogen
Answer:
a) 12.74 V
b) Two pairs of diode will work only half of the cycle
c) 8.11 V
d) 8.11 mA
Explanation:
The voltage after the transformer is relationated with the transformer relationshinp:
the peak voltage before the bridge rectifier is given by:
The diodes drop 0.7v, when we use a bridge rectifier only two diodes are working when the signal is positive and the other two when it's negative, so the peak voltage of the load is:
As we said before only two diodes will work at a time, because the signal is half positive and half negative,so two of them will work only half of the cycle.
The averague voltage on a full wave rectifier is given by:
Using Ohm's law:
