The key design factor in a VAV system is the control of. the supplied air. The terminal unit should be sized to. take advantage of as much of its potential capacity as. possible. Without this fundamental consideration, the. customer has not received the best value for their VAV. system design.
The amperage rating on the DC motor is not the amperage the treadmill will be using from your wall outlet. Most treadmills only need 10-12 amps from the wall (or less), so a 15 amp circuit is fine, regardless of the rating on the motor. Just look at the amperage rating on the treadmill to see what your wall outlet needs to supply. #2 see #1. #3 Current is always lost in the form of heat when used to power a device. Be it in the motor, the electronics or even the line supplying the current.
Ohms does not equal watts. You need to know what voltage is across the resistor to determine how many watts it is drawing or how many watts the resistor should be rated for.  â¦   Power is the voltage across the resistor SQUARED divided by the resistance.If this 4 ohm resistor has 12 volts across it then the watts power is (12 x 12) / 4 = 36 watts.  1 Watt equals 1 Volt times 1 Amp.9 people found this useful. As ohms are used to measure resistance/reactance/impedance, and volts are used to measure potent â¦ ial and potential difference, you cannot ask how many ohms equals one volt-is like asking, How many oranges equals one bicycle?.
