The electrical code states that there shall not be more than 12 outlets on a two wire branch circuit. Such outlets shall be considered to be rated at not less than 1 amp per outlet.Where the connected load is known, the number of outlets shall be permitted to exceed 12, provided that the load current does not exceed 80% of the rating of the over current device protecting the circuit.
If the lights are the load of the circuit, then the lights will be off if the circuit is open.
In a closed circuit, the lights will be on, assuming there is a power source connected to the circuit and the switch controlling the lights is turned on. This is because the closed circuit allows the flow of electricity from the power source to the lights, completing the circuit and causing the lights to illuminate.
The circuit breakers in a panelboard feed separate circuits. The lights that stay on are on a different circuit than the ones that go off. To fine the circuit that feeds the lights that stay on, go to the panelboard and turn off the breakers one by one until the lights go out. This is the circuit that feeds that circuit of lights. Remember that lights and receptacles can be on the same circuit together.
To determine if the lights and outlets in a room are connected to the same circuit, you can check the circuit breaker panel. If the lights and outlets are on the same circuit, flipping the breaker for that circuit will turn off both the lights and outlets. If they are on separate circuits, turning off the breaker for the lights will only affect the lights, and the outlets will still have power.
If the lights in a room are off, the circuit is open, meaning there is a break in the flow of electricity and the lights cannot receive power. When the lights are turned on, the circuit is closed, allowing electricity to flow and power the lights.
series circuit
15 amps at 80% = 12 amps continuous. Watts = Amps x Volts.
To design a circuit so that lights can be turned on and off separately, we connect the circuit in parallel.
A parallel circuit lights up even when one bulb is out.
If you remove one light from a chain of lights, and the other lights turn off, then it is a 'series' circuit.
Wire in a turn signal flasher in series with the circuit you wish to flash. The flasher has two terminals. Just insert the flasher anywhere in the circuit. It will make/break the circuit to make the lights flash. This is considering that the circuit is 12 volts and not 120 volts.
Yes you would use a serial circuit You would use parallel circuit lights for a Christmas tree because if you used series circuit lights, and one of the bulb blows, the rest of the bulbs will go out. But with parallel circuit lights, if one bulb blows the rest of the bulbs will remain their brightness.
