    KIRCHOFF's Law: Solving Circuit

    according to circuit In Left Loop Current is I1 and Right Loop is I2 Now Loop Left 10-8I1-3I1-I2=0 which becomes 10-8I1-3I1+3I2=0 11I1-3I2-10=0 ------------eq 1 Now Loop Right 15-6I2-3I2-I1=0 15-6I2-3I2+3I1=0 3I1-9I2+15=0 I1-3I2+5=0 ---------------eq 2 Deduct eq 2 from eq 1...

    I am confuse in finding Argumnet of Complex Number

    hi PF 1. (2+2i) First Quadrant 2. (-2+2i) Second Quadrant 3. (-2-2i) Third Quadrant 4. (2-2i) Fourth Quadrant consider (2+1i) then Tan^-1(2/2) which will be 45 degree if we consider (-2+2i) then it will be -45 degree but angle will not -45 degree actually we get answer by adding or...
