Why do I have voltage but no amps?

Why do I have voltage but no amps?

The most common cause of no amperage is a bad contact somewhere between the rectifier and the load. This can be in the buswork, at the saddle, or even where the anodes sit on the bar. If the voltage at the tank is within 5% of the rectifier’s voltage, then it is unlikely that you have a connection issue.

What does 0 volts mean?

0v, or zero volts, a complete lack of voltage.

Is 0 volts the same as ground?

The 0 volts connection on a power supply is just a reference (e.g. a 12 volt supply may have a 0V connection and a +12V connection). But if 0V is not connected to “earth” or “ground” (and many modern power supplies are not, they are isolated) then 0V is not equal to earth or ground.

Can you have voltage without amps?

There can be voltage without a current; for instance if you have a single charge, that charge induces a voltage in space, even if it’s empty. Voltage, in the most physical way, is a scalar field that determines the potential energy per unit charge at every point in space.

What happens when voltage is zero?

Kermit2. The problem you have created is to make up a ‘voltage’ for the common point. If you have ZERO volts then you don’t have a voltage therefore you have no current.

Can a circuit have voltage and no current?

Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage.

Is voltage 0 at the end of a circuit?

So, the answer is 0V, no difference in potential between those two points. They are at the same electric potential. No, voltage can exist without the resistor.

What is the zero voltage switch used for?

Zero Voltage Switching – McShane, Inc. Zero Voltage Switching means that the power to the load (heater or cooler or other device) is switched on or off only when the output voltage is zero volts. Zero Voltage Switching can extend the life of a controller and of the load being controlled.

Why is ground voltage defined to be zero volts?

You see the electric field generated imparts energy to the flowing electrons in a wire that we call current. So when it is zero voltage it just means the electrons have zero energy relative to when it first started because it was used up after flowing through devices that used the energy.

Does no voltage mean no current?

It is the force that allows electrons to move from one point to another. If the voltage is absent, those electrons cannot move between points in a circuit, which means that the current does not exist.

What happens when there is no current?

When there is no current in the wire, their is no magnetic induction. The electromagnet then is simply a coil with no magnetic field associated with it. The moment we allow a current to flow through, there is a magnetic induction and thus we get an electromagnet.
