There are many variables that affect the ratings of electrical circuits but in general:
If you are asking about residential branch circuit ratings, they are listed in amps and protected by a fuse or breaker. For example, a typical residential lighting circuit is usually a 15 amp / 120 volt circuit. It will be protected by a 15 amp overcurrent device (breaker or fuse) and all components of the circuit (wire etc) must be rated for at least 15 amps.
Common residential circuit ratings:
15 amp / 120 volt - lighting and receptacles
20 amp / 120 volt - bathroom, kitchen, dining room, workshop etc. receptacles
30 amp / 240 volt - electric dryer, electric water heater
40 or 50 amp / 240 volt - electric stove
For minimum conductor (wire) sizing, the National Electric Code recognizes many variables that affect the ampacity (number of amps) a wire can safely carry. But in most residential circuits the following copper conductors are used:
15 amp - #14 American Wire Gauge (AWG)
20 amp - #12 AWG
30 amp - #10 AWG
40 amp - #8 AWG
50 amp - #6 AWG
Aluminum is typically not used in the smaller sizes, though you may find #6 AWG used for larger (40 amp) loads

Name 4 common parts of an electrical circuit?
1. Source of electrical energy2. Electrical load3. Electric circuit control device4. Connector
What type of an electrical circuit has more than one current branch?
A parallel circuit is an electrical circuit that has more than one current branch.
What causes the main breaker to trip from a fault current from a twenty amp branch circuit?
If the fault was on the 20 amp branch circuit, the branch circuit breaker should have tripped, not the main breaker. Call a qualified electrician to check out your wiring.
Infer which type of circuit an outlet is part of?
Outlets are part of a "branch" circuit.
What is the purpose of a branch circuit?
To supply power to all electrical devices in a house, apartment, condominium, etc. A branch circuit is connected to the circuit breaker panel which is usually found in a closet or a cupboard
What happens to an electrical circuit when there is unwanted resistance in it?
a common cause of this type problem is corrosion at a connector.

What does grounding a connector mean?
"Grounding a connector" means you join a connector in a circuit to another point in the circuit that is definitely at ground potential. This is done mainly when testing a circuit, to be sure that a particular point in that circuit really is at ground potential if you are not certain that it is already. Alternatively, you could be doing a test to temporarily ground a connector that is not normally at ground potential, to see what effect doing the test has on the behavior of the circuit.
How can you identify the branch parallel circuit with the what will have the least amount of current flow?
In a DC circuit, it's the branch with the largest resistance. In an AC circuit, it's the branch with the largest magnitude of impedance.
What determines the current in each branch of parallel of circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
What determines the current in each branch of a parallel circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
What happens to an ammeter when there is a break in a circuit?
An ammeter reads the current that is flowing through a branch of a circuit. If there is a break within that same branch of the circuit, current will not be able to flow through that branch of the circuit as it forms an incomplete loop, so the ammeter will read 0 A of current. If there is a break in a circuit in a branch that is not connected to the ammeter however, the ammeter will give a higher reading of the current. This is assuming that the break in the other branch does not short out the branch with the ammeter attached, and that the circuit can still form a complete loop without that branch.
What type of an electrical circuit has more than one current branch?
A parallel circuit is an electrical circuit that has more than one current branch.
What determines the current ine each branch of parallel of circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
Is a circuit breaker required on every branch circuit?
