## Circuits, Ohm's law & resistance (Hindi)

We saw what current & voltage are. Now let's explore the connection between them, which is famously called 'Ohm's law'

## Factors on which resistance of a conductor depends on (Hindi)

What decides whether something is a good or a bad conductor of electricity? It's the resistivity of that material. So let's explore this concept of resistance and resistivity in detail.

## Series and parallel resistors (Hindi)

How to solve circuits when we have more than 1 resistor in it? That's exactly what we will learn in this lesson.
