Acceptable voltage drop for 3 phase 415 volt motor?
The voltage drop should not exceed 3% on a feeder or branch circuit.
What wire size 240 volt 21 amps 150 foot run?
A #10 copper conductor will limit the voltage drop to 3% or less when supplying 21 amps for 150 feet on a 240 volt system.
Is forward voltage drop of schottky diode more than tunnel diode?
Yes, the forward voltage drop of a Schottky diode is usually more than the forward voltage drop of a tunnel diode. A Schottky diode voltage drop is between approximately 0.15 to 0.45 volt. The interesting thing that makes a tunnel diode different from other diodes is its "negative resistance region" with a "peak current" around 0.06 volt and a "valley current" around 0.30 volt.
What is the Voltage drop for 70 foot run 300 watt 12 volt ac circuit?
IF USING A COPPER AT 105 DEG. CELSIUS - 70 FT. ONE-WAY LENGTH: TO GET AT VOLTAGE DROP = 3.72% AT 25 AMP LOAD ---- USE #1 AWG TO GET AT VOLTAGE DROP = 2.94% AT 25 AMP LOAD ---- USE #1/0 AWG TO GET AT VOLTAGE DROP = 1.85% AT 25 AMP LOAD ---- USE #3/0 AWG
What is the volt drop across a 10k resistor with a 5 volt supply?
If there is nothing else in the circuit, then the voltage drop across the resistor will be the full supply voltage of 5 volts. The size of the resistor does not matter in this case - it will always be 5 volts.
What size wire for 110 volt 20 amp circuit 700ft?
I would recommend no smaller than #8awg copper. This is derived by 8awg copper ampacity of 40 amps multiplied by 80% load rating to get 32 amps. Then calculating for voltage drop over this distance shows a drop of 5.9 volts or 2.5% which is negligible so not accounted for. So like i said no smaller than #8awg copper.
What do you use to check for line voltage sags?
Voltage drops need to be checked with a volt meter. Depending on where the drop is thought to be, the meter can be connected an wiring plugs to find where the drop is.
How do you get 12 volts from an 18 volt transformer?
Reduce the primary voltage and the secondary will also drop.
What is the permissible voltage drop in a 120 volt power supply?
5% from source to farthest load.
What is the purpose of transmitting electricity at high voltage?
Less current, greater efficiency, reduced volt drop
What is the purpose at transmitting electricity at high voltage?
Less current, greater efficiency, reduced volt drop
Why isn't there voltage drop in a 240 volt system?
Regarding the question of "Why isn't there voltage drop in a 240 volt system?" The smart alex answer is "because no current is flowing." Only if no current is flowing can there be no voltage drop in any circuit. All conductors, even supercondutors, have resistance and this resistance will produce a voltage drop when a current is flowing through the conductor(s). 240 volts is used over 120 (or 12 volts) because it reduces the current reguired for a fixed amount of POWER (watts). Therefore, the conductor size can then be reduced to reduce cost, size, weight or to improve flexibilty.
