RMS (Root Mean Square) Value of AC and Alternating EMF
AC can be defined in terms of the heat produced in a resistor due to motion of charges. The effective value (I r m s or I e f f ) of the AC is defined as the value of that direct current which produces the heat at the same rate as the alternating current in a given resistor. The AC is represented a..

Time Period of Oscillation Varies with Time
. But the above table does not tell us whether the length and time period are directly proportional or not. By plotting a graph between L and T we can come to know whether L and T are directly proportional or not. We plot a graph by taking L along x axis and T along y axis, Graph between ..
