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.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
