Answer:
One Foot
Explanation:
The general rule is to maintain a distance of one foot per four feet of height.
Answer:
12 volts
Explanation:
The voltage ratio is equal to the turns ratio.
secondary/primary = 20/200 = v2/120
v2 = 120(20/200) = 12
The secondary winding voltage is 12 volts.
Answer:
The equation used to solve a diode is

is the current going through the diode
is your saturation current
is the voltage across your diode
is the voltage of the diode at a certain room temperature. by default, you always use
for room temperature.
If you look at the equation,
, you'd notice that the
grow exponentially fast, so we can ignore the -1 in the equation because it's so small compared to the exponential.


Therefore, use
to solve your equation.
