Some magnetic flux is changed from a coil of resistance 10Omega. As a result an induced current is developed in it, which varies with time as shown in figure. What is the magnitude of change in flux through the coil ? |
Answer» SOLUTION :The INDUCED charge is `q = (Delta phi)/(R )`  But, AREA of i-t CURVE GIVES charge ` therefore Delta phi = R xx ` area of i - t curve ` Delta phi = qR = 1/2 xx 4 xx 0.1 xx 10therefore Delta phi = 2wb` |
