As they are connected in parallel (each has its own branch) the remaining bulbs keep shining exactly as they did before.
Dear Wiki Questioner, When you disconnect a light bulb from a series circuit, the entire circuit is broken and no electricity can flow around it... so everything else on the circuit looses access to the power source! You can think of a series circuit as a relay race, where the runners are the bulbs and wires (and anything else that is connected to the circuit). If any one of the runners in a relay race is taken out of the race (say by a sprained ankle), the relay gets stuck and the team cannot complete the race (that is to say, the electricity cannot make a complete circuit). Of course, if you plug that runner back into the system, the race continues as usual!

the thermistors respond negatively to the temperature and their resistance decreases with the increase in temperature. Since the resistance of thermistors is dependent on the temperature, they can be connected in the electrical circuit to measure the temperature of the body.

Yes it will show .It is because if electric current is passed through the wires then it will become an electromagnet and show magnetic properties.But there should be a circular coil in the circuit then only that part will show magnetic properties.
If you have a 3 bulbs in parallel lets say. If one of those burns out it just means that there is now an open circuit where the burned out bulb used to be. The two that remain aren't aware that anything has changed.
oppen circuit
No change in supply voltage as additional resistance is connected in parallel circuit.
The other components are still connected to the circuit
When a switch is open (wires not connected) it is considered off. When a switch is closed it is considered on. If you move a switch and the wires are not connected the the circuit is open and current cannot run throughout the circuit to power the device.
the current flowing in will be low
nothings because they is no wire connected to the circuit so no current can flow through
Please re define "If an insulator with a lamp"
The lamps will get dimmer. In a parallel circuit, voltage is constant. Whereas, in a series circuit, amps are constant.
To close a circuit in electrical terminology is to close any open devices that are in series with a connected load. Once this happens the current will flow through the load and the load is then termed as energised. In the case of a motor circuit the motor will operate. In the case of a lighting circuit the lamps in the circuit will energise and light the area in which they are installed.
If the coil is connected to a circuit and the switch is closed then, provided there is a power source, the coil will become energized.
All of the light bulbs in the series circuit would go out.
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
