Hi, in this question we have an rlc circuit which is driven by this ac generator having the value of frequency f as 112 hertz.
00:12
So now in part a of this question, they're telling us that the value of resistance r is equals to 270 oom.
00:22
The value of inductor l is given as 0 .734 henry and the capacity.
00:30
Acetin c is given as 6 .26 microperad.
00:36
So we have to calculate the impedance of the circuit.
00:40
So the impedance of the circuit is given as z is equals to under root r square plus 1 upon omega c minus omega l whole square.
00:55
So now first of all, we have to calculate the value of omega, so, omega is basically given as 2 pi f.
01:06
So, we can calculate the value of omega as 2 into 3 .14 into 122 hertz.
01:14
So from here, we'll get the value of omega as 766 .2 radiance per second.
01:23
So now, we can write z equals to under root.
01:28
Basically, r is given as 270.
01:29
So this will be 270 square plus 1 divided by 766 .2 multiplied by c, which is 6 .26 into 10 raised to power minus 6 .6 since it was in micro ferrat minus omega, which is 766 .2 into l, which is given as 0 .734...
