What is the setting in air circuit breaker?
"The setting" is not clear. There can be lots of stuff in a breaker control cabinet that could be deemed to have a "setting".
How do you know when you have a circuit?
tuned circuit
But in DC ciruit there is no current when capacitor is connected?
This is because when you introduce a capacitor, the circuit is no longer a DC circuit. If you're using a multimeter see if there is an AC setting to measure the current.
How do you calculate setting for over current earth fault relay setting?
An artificial neutral is crated in the CT of the line to be protected (for transmission lines) a CT is fixed in the neutral of the CT. if there is any imbalance in the 3 phase current then the relay will develop a difference in neutral.that can be sensed by the CT,then gives the trip command to relay
What effect if any does connecting an ammeter in series with a resistor in a circuit have on the current through resistor?
The Amp meter was design to allow current flow through the meter to measure with a minimal alteration to the original circuit. That is the ideal world, in reality the meter has some resistance and will lower the current flow. The multiple current setting on most meter will reduce the effects caused by the meter but you must be careful not to damage the meter by reading to high for the setting.

What is the requirement for energizing a 120 volt circuit breaker?
Before energizing a breaker for a circuit, the circuit has to be clear of any short circuits or grounds. This can be accomplished by the use of a megger on the correct voltage setting.
When setting up a breaker box how do you determine circuit breaker capacity?
find amphere required
How do you know when you have a circuit?
tuned circuit
What is a track called that ends up where it started?
A circuit
How do you define transistor biasing?
Selection and setting of a transistor's operating pointto meet circuit functional requirements.
But in DC ciruit there is no current when capacitor is connected?
This is because when you introduce a capacitor, the circuit is no longer a DC circuit. If you're using a multimeter see if there is an AC setting to measure the current.
When you connect a multimeter across an open component what is the reading?
That will depend on the setting of the meter switch and the circuit connected to the component (if there is one).
In The USA How many outlets can be hooked up on a 20 amp circuit?
Rule of thumb is about 8 unless it is a dedicated circuit. The NEC has no requirements on the number of receptacles that can be on a circuit in a residential setting. The circuit should be layed out to only cover 500 sq. feet. A single room of 500 sq. feet, you could put as many receptacle as you want on one circuit.
How do you check for amps?
You need to use an ammeter - usually the current setting on a multi-meter. The meter should be connected to the circuit in series.
How would someone run a circuit board test?
You can run a circuit board test by using a multimeter with the ohmmeter setting. Turn the multimeter to the lowest setting and touch one lead to the tester at the solder point and the other to the socket. The resistance should read 0. A reading of infinity signifies a bad connection and will need to be re-soldered.
Why does your multimeter keep blowing its fuse?
always have multimeter on the highest setting and always Disconnect it from the CIRCUIT BEFORE switching from one measurement to another.
