Formula:
I =Amps/Volume of current
E = Volts/Force moving the current
P = Watts, Electrical power produced
If transformer I x E=P
primary=120v and 12 x 20=240watts
secondary 12v=20 amps, In a transformer watts stay the same so now:
what are the amps on the P/E=I
primary? 240/120v=2 amps
6.0 watts.
If 17.32v are applied Formula: V squared/R = P
across a resistance of 50 17.32 squared(299.98)/50=5.99
ohms, how much power is
expended in the resistor?
A space that:
-is large enough to enter and work.
Confined Space -has limited or restricted means for entry.
-is not designed for continuous occupancy.
An employer's written authorization to perform work
Hot Work Permit capable of providing a source of ignition.
A form of purging or ventilating a confined space where
an inert gas (such as nitrogen, carbon dioxide or argon)
is used to displace the atmosphere in a confined space
to remove fire or explosion hazards. Causes oxygen
Inerting levels to become unstable for re-entry.
19.5% to 23.5%
Below 19.5=unsafe for breathing
Oxygen Safe Zone Above 23.5=explosive
The part or area of a drawing to which a number, note
or other reference applies. They are solid lines and
Leader Line usually terminate in a single arrowhead.

Hydraulic Term:
more pressure to pass the same amount of water.
"Resistance"
Electric potential is equivalent to pressure and the
Hydraulic Term: voltage (or voltage drop/potential difference) is the
"Voltage" difference in pressure between two points.
(Assume water is flowing
horizontally so gravity isn't
a factor)
Equivalent to a hydraulic volume flow rate; that is the
Hydraulic Term:
"Current" volumetric quantity of flowing water over time.
Current through a conductor between two points is
directly proportional to the voltage across the two
Ohm's Law points.
