When a switch is closed the path through the circuit is continuous.
In a series circuit, all the current passes through the one circuit. Any break will totally remove power from all of the circuit.Parallel circuits have more than one branch where the current can flow. A broken wire will only affect one part, the rest of the circuit will still pass current.In a series circuit, all the current passes through the one circuit.

Because a switch is a 'permanent' action. A relay only completes the circuit while there is power. If there is a fault in the circuit, a switch will still allow power through, whereas a relay will break the circuit.
parallel circuit: Providing that the breakage does not result in a short circuit the other bulbs will still light. series circuit: If the breakage results in a short circuit through the bulb the other bulbs will light more brightly. If the breakage results in a breakage of the connection through the bulb then the other bulbs will not light.
The battery is the power source of the circuit. It supplies current to the circuit and the circuit is simply a path for the current to follow. When you remove the current (battery), the path still exists but there is no current going through it.
There are two types of circuits: series, and parallel. In a series circuit, electricity flows through all components of the circuit in a series. This means it flows from the power source, through all the components as a whole, then back to the source. A parallel circuit, on the other hand has the electricity flow through the components separately. Power flows from the source to each individual component individually, then back to the source. In a series circuit, if one component is missing or broken, the circuit will not function. With a parallel circuit, on the other hand, if a part is missing, or broken, all the other components will still work.
By connecting it to a circuit with the power still applied. Ohm meters work best when the component under test is removed from the circuit to eliminate parallel paths of current through other components.
The Catalytic Converter is an emissions control device on your car and can be disabled (illegally). Your car will still have power if it is broken/disabled but will fail emissions.
because the power still are in circuit of the motherboard and you have to drain the system
If the bulb's filament is broken, the whole circuit becomes open. If the bulb is in a series circuit or is the only bulb, the electricity would no longer flow. If the bulb is in a parallel circuit, along with other bulbs, then only the blown bulb would go out, and the other bulbs would still work.
an ohmmeter contains its own power source that it uses to test the circuit. if power is still on in the circuit, at the least the meter will give incorrect readings, at the worst the meter may be damaged rendering it useless.
Possibly. If it still works when you turn it on, the of course it is using power. If it does not work when it otherwise would, then it is definitely not using power, just as if you didn't have the bulb there at all. <<>> With the voltage on the circuit and the light bulb in the circuit, the bulb will glow. If you unscrew the bulb until it goes out the potential voltage will still be in the circuit but no current will flow so no power will be used. In this scenario the unscrewing of the bulb will be the same as using a switch in the circuit to interrupt the current flow.
