Hello students.

An inductor and resistor are placed in series and are connected to an ac source of frequency f equals 60 hertz.
00:17
What would be the impedance of this circuit and the phase difference between the current and the applied voltage if the resistance is 10 oms and inductance is 25 millie henry.
00:37
Now let us say this is the circuit in which there is an inductor and a resistor connected in series to an ac source of frequency 60 hertz.
00:58
Now this is l and this is r.
01:02
The impedance of the circuit is z equal equals root of r square plus xl square.
01:17
Xl is omega into l, that is, omega is 2 pi f into l.
01:24
So 2 into let us take the value of pi as 3 .14 into frequency 60 into l, 25 into 25 into the part minus 3.
01:33
Now upon multiplying all these things, 2 into 3 .14 into 60 into 25 will give 9 ,040 into 10 to the power minus 3, that would be xl is 9 .42 oms.
02:01
Now let us calculate the value of impedance...
