What happens when you close a circuit?
If there's a lightbulb it lights up, but basically it lets energy flow through, which completes it.
What are the differences between series circuit lights and parallel circuit lights in terms of energy changes?
In a series circuit the lights share the voltage between them equally and the current stays the same throughout and if one bulb fuses the the other will not work. For the parallel, the voltage is the full voltage from the battery in all bulbs and the current is split between the different routes, and if one goes out the other one will stay lighten.
Are street lights on a series circuit or a parallel circuit?
Parallel. One light burning out does not stop all current flow to the other lights.
If the lights in a room are off the circuit is?
Open.
How does it save energy to turn off lights?
Lights use energy. Turning them off saves energy.
What is the job of a bulb in a circuit?
The job of the bulb in a circuit is to convert electrical energy to light. It's called the load in the circuit.
Are lights onor off in an open circuit?
If the lights are the load of the circuit, then the lights will be off if the circuit is open.
What happens when you close a circuit?
If there's a lightbulb it lights up, but basically it lets energy flow through, which completes it.
In an closed circuit will the lights be on or off?
Lights are on in closed circuit. It means that is a current flowing when circuit is being closed.
What are the Products of the light reactions of photosynthesis that provide energy for the Calvin cycle are?
They are called LIGHTS
When a home circuit breaker opens the lights in some rooms go off but the lights in some rooms stay on. Explain why.?
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.
What are the products of light reactions and photosynthesis that provide energy for the Calvin cycle called?
They are called LIGHTS
Are fluorescent lights on a parallel circuit or a series circuit?
series circuit
In an automobile a 12 Volt battery simultaneously supplies electrical energy for the ignition lights and radio. This electrical circuit must be?
The battery must be able to provide enough power, to make all this work. Also, it must be able to store a reasonable amount of energy, in order to last for a reasonable time.
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.
What is a circuit that lights up even if one bulb is out?
A parallel circuit lights up even when one bulb is out.
What are the differences between series circuit lights and parallel circuit lights in terms of energy changes?
In a series circuit the lights share the voltage between them equally and the current stays the same throughout and if one bulb fuses the the other will not work. For the parallel, the voltage is the full voltage from the battery in all bulbs and the current is split between the different routes, and if one goes out the other one will stay lighten.
