Why do I get incorrect voltage feed back?
One of the main incoming lines has a loose or burnt connection (my guess is L2 because L1 to N reading is correct) or you have an Open Neutral, which could be a loose or burnt connection as well. Roy, your getting a voltage feed-back due to one line that has been lost.
Why does my multimeter not read my voltage regulator?
This voltage reading should typically be around 1-2 volts higher than what the regulator is designed to output. If your multimeter doesn’t read anything, it means that your regulator isn’t properly receiving current from your power supply or that the meter is not connected to the correct pins on the regulator.
What should the voltage reading be on a voltage regulator?
Attach the red wire to the input pin and the black wire to the ground pin. Doing this will give you the input voltage reading. This voltage reading should typically be around 1-2 volts higher than what the regulator is designed to output.
What are the signs of a bad voltage regulator?
Signs of a bad voltage regulator in a vehicle include dimming or pulsing lights or a dead battery. If you have electrical equipment that won’t turn on, that could also indicate a bad voltage regulator—the regulator could either be letting no power through or letting through too much and damaging the other components.
How is the voltage across the resistance determined?
In summary, the voltage across the resistance (in this ideal circuit) is not determined by Ohm’s law, it is determined by the battery. When the resistance is ‘infinite’, the current through is zero by Ohm’s law.
Why is the voltage drop across a resistor the same?
In a parallel circuit, the voltage drop across each resistor will be the same as the power source. Ohm’s Law is conserved because the value of the current flowing through each resistor is different.
When is the voltage not determined by Ohm’s law?
In summary, the voltage across the resistance (in this ideal circuit) is not determined by Ohm’s law, it is determined by the battery. When the resistance is ‘infinite’, the current through is zero by Ohm’s law. Note that there is difficulty if we allow the resistance to go to zero.
