ammeter
Current transformers are used to measure electric currents. When current in a circuit is too high to directly apply to measuring instruments, a current transformer produces a reduced current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments.
Voltage causes current to flow in an electric circuit.
Voltage causes current to flow in an electric circuit.
The term is "circuit" (from the same root as circle) An electric circuit must be uninterrupted for the current to flow. (This is why circuit-breakers are also called circuit-interruptors.)
A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.
I guess Electric Circuit....
The electric field in a circuit is directly related to the current flowing through it. The electric field is what drives the flow of electric charge, which is the current. In other words, the presence of an electric field is necessary for current to flow in a circuit.
If the electric circuit is broken, there will be no medium for transfer of electrons and flow of current. Hence, electric current does not exist.
The name for the status of a circuit that has breaks which electric current that can't flow is called a Closed Circuit. Electric current cannot flow through an open circuit.

Potential . . .Always measured as a potential difference between two points.The most practical way to do that is with a voltemeter connectedin parallel with any circuit between the two points.Electric current . . .The most practical way to measure current is with an ammeter connectedin series in the path of the current.
