volt drop

[Peter Woodford]

can someone help me in understanding voltage drop please. can't remember much about it

 

[Amp David]

Is this a wind up?

 

[bugsy]

Can you please be more specific about the bit you don.t understand

Liken the voltage to a guy carrying a sack of spuds over a distance

There is a particular effort all the way along,so he is losing energy right the way through.its a resistance ( resistivity of the conductor)

Every time he climbs an hill ( a load ) he loses energy because of the extra effort

The amount he loses depends how steep is the hill,or( how high rating the load)
If there are a few hills along the way.they are loads in series and energy is lost through each one

By the end of the journey as long as we know the start energy the energy needed to get through the loads and the all along the way effort, we can measure or calculate whats left at the circuit end


Voltage drop in a different light ( get the pun )

voltage drop 3% for lights so 6.9volts max 5% everything else so 11.5volts max. Off the top of my head

Volt Drop = mva/m x Design Current x Cable Lenght divided by 1000

Hope that helps

Why doesn't he seal the sack then?
Then he won't drop any spuds.

No, the spuds are his fuel. The hill is his fear of mortality.

His journey is a courageous one.

Question for today,
if you dropped voltage would you pick it up?

 

[Bromd123]

OR

If voltage was dropped an no one was around would it make a sound?

 

[ezzzekiel]

OR

If voltage was dropped would it hurt itself
