Answer 1

Solna As me can see from the figure that ammeter is reading both I, and Iz ule can say I + I2 - (1) Since ammeter is reading 2A. = 2A 15V 72 II + I2 GII loop! 59 (I2 loop 1,1 22 E taking loopt and applying kut law -15 + 7I, + (I t I ₂) 5 = 0 | 12 I, + 5 I ₂ = 15 taking loop 2 we get - E + 2 I2 + 5 (I, + I2) = 0 5 I, + 7 I2 = c = 0 T. E= 5 I, +7 Iz taking eq (1) and (2) we got. 0.7142851 12 I, + 5(2-I) = 15 12 I, + 10-5 I, = 15 7I = 5 I, = 5 7. putting it in (1) we get = 1.2857 32

Now putting both value in eq ③ we get. E = 5 x (0.7142857) + 7(1-2857) 3.571428 + 8.9999 - 112.5713 Ans
