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'.

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.
Why does gfci breaker trip when something is turned on a separate circuit?
A GFCI breaker trips when a device is turned on a separate circuit because it detects a ground fault or an imbalance in the current flowing through the hot and neutral wires. This can happen if there is a shared neutral between circuits, leading to a difference in current flow that the GFCI interprets as a potential shock hazard. Additionally, if the device being turned on has a fault or if there are issues with wiring, it may also cause the GFCI to trip for safety.
What device can break an electric circuit?
There are 2 different types of these devices: circuit breakers (which can be reset after the problem is fixed) and fuses (which must be replaced after the problem is fixed).
A circuit with a switch turned to the Off position or a circuit with any break is called?
a closed circuit
