CBSE CLASS 10 SCIENCE CHAPTER 12 ELECTRICITY NOTES - (PART IV) NOTES OF CH 12 ELECTRICITY, CLASS 10TH SCIENCE Study Material and Notes of Ch 12 Electricity Class 10th Science Remaining Topics of this Chapter 10. HEATING EFFECT OF ELECTRIC CIRCUIT A. JOULE'S LAW HEATING EFFECT OF ELECTRIC CURRENT B. The FILAMENT OF AN ELECTRIC BULB IS MADE UP OF TUNGSTEN C. ELECTRIC FUSE D. ELECTRIC POWER HEATING EFFECT OF ELECTRIC CIRCUIT If an electric circuit is purely resistive, the source of energy is continually dissipated entirely in the form of heat. This is known as the heating effect of an electric current. As E = P × T ∝ VIt {E = H} Heat produced, H = VIt {V = IR} Or, Heat produced, H = I 2 Rt USES OF THE HEATING EFFECT OF ELECTRIC CURRENT The heating effect of current is applied in t...
