Скачать или смотреть JEE MAIN PYQ: 64- change in resistance of wire when length of wire is changed

In this video, we’ll explore an important topic in Electric Circuits & Resistivity — how the resistance of a wire changes when its length is altered, a concept frequently asked in JEE Mains and NEET ⚡

You’ll learn:
✅ The relationship between resistance, length, and cross-sectional area ()
✅ Step-by-step method to calculate new resistance when the wire is stretched or shortened
✅ Effect of changing length on resistivity and resistance
✅ Detailed JEE Mains & NEET PYQs solved with clear explanations
✅ Tricks, shortcuts, and conceptual tips to solve wire-length problems efficiently
✅ Common mistakes students make and how to avoid them

By the end of this session, you’ll confidently calculate resistance for any change in wire length and solve related PYQs with ease.
