High resistance on the feeder to the load will cause voltage drop at the load end of the circuit. If this is happening, do the calculations for voltage drop, using the amperage of the load, voltage of the load, the size of the wire feeding the load and the distance from the distribution panel to the load.
What else can I help you with?
What cause the voltage drop in shunt generator when its loaded?
because the voltage likes to drop
Should there be voltage readings across a closed contact?
For all practical purposes NO. The only voltage measured will be the voltage drop of the contact itself. This should be very low if the contact is good.
I have a 5000 watt Honda generator. How much of a voltage drop will a 25 foot portable generator cord cause?
A 25 foot cord will not cause enough voltage drop to worry about.
What is voltage drop per foot?
Voltage drop is caused by resistance. From the equation V=IR the voltage across that resistance can be calculated. For a uniform conductor the resistance is linear with the length R=kx where k is in ohms per foot. For a given current, the voltage drop V=Ikx so the voltage drop per foot is Ik. Voltage drop per foot can be measured, allowing a calculation of voltage drop for very long lengths of conductor such as power transmission lines. This is a reasonable approximation as long as the total voltage drop in transmission is small relative to the supply voltage. If the voltage drop is large, the current will be limited by the total resistance. This implies that long distance transmission lines should be high voltage, because 1 megawatt at 10,000 volts requires 100 amps, while at 100,000 volts it only requires 10 amps. The voltage drop per foot for the same conductor would be 10 times as large at 10 times the current, and the power loss (I*IR) would be 100 times as large. For alternating current, inductance can be a factor; this implies that relatively low frequency would be preferred.
What is the difference between voltage forward voltage and voltage drop?
Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.
Can a corroded battery cause a voltage drop?
Yes, a corroded battery can cause an intermittent voltage drop.
How can I test voltage drop effectively?
To test voltage drop effectively, use a multimeter to measure the voltage at the source and then at the load. The difference between the two readings indicates the voltage drop. Ensure all connections are secure and check for any signs of corrosion.
What cause the voltage drop in shunt generator when its loaded?
because the voltage likes to drop
What does a voltage drop test measure and how is it performed?
A voltage drop test measures the amount of voltage lost as electricity flows through a circuit. It is performed by connecting a voltmeter to different points in the circuit and comparing the readings to determine if there is excessive resistance causing a voltage drop.
Should there be voltage readings across a closed contact?
For all practical purposes NO. The only voltage measured will be the voltage drop of the contact itself. This should be very low if the contact is good.

What would be the voltage drop across two 25 resistors in parallel if the source voltage were equal to 9v?
The voltage would 9V minus any drop in the battery.
What is the cause of voltage drop in electrical circuits?
Voltage drop in electrical circuits is caused by the resistance in the circuit components, such as wires, connections, and devices, which leads to a decrease in voltage as current flows through them.
What would cause my outside temp display on my 2001 Buick Century Limited Climate control drop to -38 degrees when it's 60 degrees outside?
If the sensor is blocked or has mud on it, the readings will be inaccurate, and give completely false readings.
Why would the volt meter bounce when the turn signal is on in a 1994 Buick Regal?
It all depends on where you are reading the voltage. If you are reading it at the bulb, then every time the light turns on, the current that it is drawing will cause the voltage to drop slightly due to resistence in the line from the battery and the corresponding voltage drop to the bulb. If there is a very large drop, there could be a short in the line with that bulb. The bulb would not get full brightness then.
What would the results of voltage drop test be if the circuit is open?
voltage drop is zero bcz in open ckt current will be zero
How do you calculate The Percentage Voltage Drop?
The percentage voltage drop is calculated using the formula: [ \text{Percentage Voltage Drop} = \left( \frac{V_{drop}}{V_{supply}} \right) \times 100 ] where ( V_{drop} ) is the voltage drop across the load or conductor, and ( V_{supply} ) is the supply voltage. Measure the voltage at the load and subtract it from the supply voltage to find ( V_{drop} ). Then, apply the formula to express the voltage drop as a percentage of the supply voltage.
