this is a MCQ no...? so is there a simple method for soving this......? i think this method will take around 3mins or 4 to solve. Also how do we think quick to draw the curcuit as mentioned..? Please tell me a way to learn much more about Electicity......im in little bit reverse of those MCQs
I think you are talking about the question No (i). The critical point is to redraw the circuit as shown. It is actually the experience. First you should solve simple problems to get that experience and then try to solve difficult ones. You should never give up until you get that ability. If you are confident about V=IR, and you are good in mathematics(You must be) then this will not take much time. However don't think that the time allocated for an MCQ is exactly 2 mins. It may be from several seconds to even 4 minutes sometimes. If you have more problems pls ask.
You can think about simple ways. But those ways cannot be explained like this, because some parts has to be done using your mind. Again that is the experience.
