Hi, in this question, we have two impedances, z1 and z2, connected in parallel.
00:06
So the first branch takes a leading current of 16 ampere, and it has a resistance of 5 ohm, while the second branch takes a lagging current of i2.
00:21
So this is i1, r1.
00:22
So i2 is given as 0 .8 pf, and the applied voltage is given as 100 plus j, 200 volt, and the total power is 5 kilowatt.
00:38
So they're asking us to find branch impedances, total circuit impedance, and branch current, and total circuit current.
00:47
Now, first of all, we know that power p is equals to v into i, so power is 5 ,000 watt, voltage is given as 100 plus j into 200 into i.
01:05
So we can calculate the value of current i as 10 minus j into 20 ampere.
01:15
Now, impedance z1 can be calculated by current to voltage...
