Find the value: 
I can do it by substituting each individual term with i,-i,-1 or 1. But is there a way to generalize this type of question, like make a formula for solving it easily?

Now I get it. Thanks!
#5 Re: Science HQ » Current » 2016-10-01 01:44:45
I got the correct answer. But I am confused about how you arrived at the equation in the third line.

Are you supposed to solve by Ohm's law or Thevinin's theorem?
I have only been taught Ohm's Law.
I have solved that the current through the battery is 2 Ohm but I cannot find the current that goes in the individual parallel resistors.

It would be appreciated if you could provide a detailed solution for the following question.
In a cyclic quadrilateral ABCD side AB and DC are produced to meet at point P and AD and BC are produced to meet at point Q (both P and Q are outside the circle). Find the value of ∠PTQ where PT and QT are the bisectors of ∠APD and ∠AQB respectively.
