Lighting circuits (UK) are fused at 15A. If in doubt, check the fuse/MCB. Unless the 7A device is lighting, connecting it would be illegal in the UK. Don't forget anything else on the same circuit.

How many amps equal 1 circuit?
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
How can one stop a portable AC unit from shutting off the circuit breaker?
Don't overload it. Your circuit may not be large enough. If it is 15 amps at 110 volts I'd bet that's it. If it shares a circuit with lights or other equipment that may be a major factor also.
Will using an outdoor extension cord to a shed with 14-2 gauge wiring cause an overload with the circuit?
To start with a #14 conductor is rated at 15 amps. An overload is any current rating above what the conductor can legally carry. So to answer the question, as long as the amperage stays below the conductor rating of 15 amps no overload will occur. Depending on the length of the cord to the shed it could cause you some low voltage problems because as the voltage drops due to line loss the current will go higher. This is especially true is a motor is connected to the circuit in the shed.
Is it safe to use a 20 amp circuit for lighting runs?
Yes : but in a residential case a 15 amp circuit would be better
What is meaured in amps?
The electrical current in a circuit is measured in amps.
What are the typical loads of electricity found rural domestic in United kingdom?
Lighting circuit - 5 amps Ring main - 13 amps Cooker circuit - 30 amps
What is a 8a fuse?
A device that will protect an electrical circuit from overload up to a current flow of 8 amps
Function of a breaker?
The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard. For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps. The short answer is to keep you safe.

What do amps do in a series circuit?
The amps (ampiers) decrease when in a series circuit ( with a light bulb)

Is a dedicated circuit for floor outlets necessary?
It depends on what the amperage of the connected load is. If it above 10 amps on a 15 amp breaker then make is a dedicated circuit. If it is used for lamps in the center of a room, then the floor outlet can be incorporated into the regular lighting and receptacle circuit.

How many ohms is a 120 volts?
"Volts" is electrical pressure applied to a circuit; whereas, "ohms" is electrical resistance to that pressure. One cannot determine ohms from voltage without knowing either the current (in "amps") or power (in "watts"). A normal 120V household circuit can handle a maximum of 20 amps, so using ohm's law of resistance = voltage / current, the minimum resistance required in a 120V household circuit would be 6 ohms. Any less than 6 ohms will cause the circuit breaker to trip.
