Sunaina made an electric circuit to lit up an electric bulb. But to her astonishment the bulb did not glow. Help Sunaina to find out the various possibilities of the bulb not glowing.

See the explanation below.

Explanation:

There are several options so that the bulb does not work in the electrical circuit, we will analyze the possible causes and explain them.

For the circuit to work it must consist of the following elements, power supply, connection wiring, and electrical bulb or lamp. These elements should work in a closed-loop, as we can see in the attached picture below.

The voltage source (battery) does not work

There is a possibility that the voltage source is discharged or does not work properly in this way the current necessary to make the bulb illuminate can not be generated.

The connection wiring is damaged

One of the most common possibilities is that at some point in the circuit, the cable is cut. In this way the current can not flow freely in the electrical circuit, without current it is not possible for the bulb to illuminate or work.

The bulb is damaged

When the bulb is damaged, the circuit is open i.e. it works as if the connection cable was open.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
