hi guys
i am a newbie
and i have 2 question which probably very easy for you guys..
so on the first picture i didnt understand why the i1 direction is like that..shouldnt it be the way i draw (with red ) and equation should be i1=i2+i3 or am i missing something ?
and can you guys explain me the second question..why the answer is 1A .i mean it should be 1A if that current source wasnt there..but doesnt it have any effect on the circut ?? can you explain me what does that current source and how should i solve question like these if there is a current source in it
