An amp meter measures current flow, not power. An amp meter measures instantaneous current either by being inserted in series with the wire being measured for current flow, or clamped onto a single current carrying wire and measuring current flow by induction. If the load is disconnected then no current will flow and the amp meter will read zero.
CommentThe correct term is ammeter, not 'amp meter'.
What else can I help you with?
How do you de-energize a circuit?
To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.
Is a switch needed to make a circuit work?
Yes, a switch is needed to control the flow of electricity in a circuit. It allows you to open or close the circuit, which determines whether the electrical current can flow through it or not. Without a switch, the circuit would be always on and the device connected to it would not be able to be turned off.
How do you make a circuit so the lights can be turned on and off separatley?
To design a circuit so that lights can be turned on and off separately, we connect the circuit in parallel.
What device can break an electric circuit?
A switch or a circuit breaker can break an electric circuit by interrupting the flow of electricity. When the switch is turned off or the circuit breaker is tripped, the circuit breaks, stopping the flow of current.
A circuit with a switch turned to the Off position or a circuit with any break is called?
a closed circuit
What meter must NEVER be connected to a circuit when the circuit power is turned on?
An Ohmmeter.

4 meters = 400 centimeters
What is a three-way switch and how does it function in a typical electrical circuit?
A three-way switch is a type of electrical switch that is used to control a light or other electrical device from two different locations. It has three terminals and allows the circuit to be turned on or off from either switch. In a typical electrical circuit, the three-way switch works by allowing the flow of electricity to be redirected between the two switches, depending on their positions, to control the connected device.
