Came here after school's practical exam for rectifying my wrongdoings and the way you explained just cleared EVERY SINGLE DOUBT i had. Schools couldnt even clear it. I wished i saw this before.

[@ConceptBuilder]

Thanks Dear

The way you tackle complex problems step by step is immensely helpful. It's like having a virtual tutor guiding me through the challenges of electrical engineering. Thank you for your dedication!

What is the reistance of rheostat used Sir?

[@ConceptBuilder]

Rheostat ka resistance variable rehta hai....we can adjust its value by slider
