Hello, students, welcome to the beautiful chapter of current electricity. Students, from this module onwards we will discuss some instruments and our first instrument is galvanometer.
So, let’s start with the galvanometer. My dear friends, it is a device which is used for detection and […]

Hello students, welcome to this beautiful chapter called as current electricity. So, the agenda for the today’s module is Kirchhoff’s Voltage Law. This is very important law as this is going to be the future of this chapter. So, let’s start with it.
So, what […]

Hello, students, welcome back to the chapter of alternating current. In the first module we have already discussed, what do we call as a direct current. A current that is constant or variable but does not change its direction in the interval of time is called […]

Hello students, welcome back. So, we were discussing certain properties of charge as well as methods of charging. Now, let’s apply them in some examples. So, let’s start with example number one.
A glass rod is rubbed with a silk cloth. Glass rod acquires a […]

Welcome back, students.
So, students, till now we have been dealing with examples of field and cases of field due to discrete charges. There was a charge or two point charges or multiple charges placed at different, different points. Now, let us discuss the case […]

Welcome back, students. So, students in previous module we had just mentioned potential due to various continuous charges. We learnt potential due to ring of charge, due to an arc of charge. More over we also talked about potential due to a line of charge. Now, […]

Hello, students, now let’s study magnetic flux before we move onto electromagnetic induction. Now same as electric flux, magnetic flux is also defined as the surface integral of the normal component of the magnetic field passing through that surface. And here the SI unit of magnetic […]
