can you do both question please this is my second time i ask the same question but i didn't get the right answer please can you do it both thanks

Please label the answer for both question if you didn't label its hard to understand the answer thanks

1. For the circuit shown in the figure below, calculate the following quantities. (Assume

and

R = 9.00 .

)

(a) the current in the 2.00- resistor (Enter the magnitude.)

2. What are the expected readings of the following in the figure below? (R = 8.80 , V = 6.40 V)

(a) ideal ammeter

1A.

i1 is current in upper loop and i2 is in the lower loop

by kirchoff rules

-12 = (4 + 2)*i1 - 2*i2

-12 = 6*i1 - 2*i2 .....(1)

-E = -2*i1 + (2+R)*i2

-9 = -2*i1 + (2+9)*i2

-9 = -2*i1 + 11*i2

-27 = -6*i1 + 33*i2 ......(2)

add equation 1 and 2

-39 = 31*i2

i2 = -39/31 = -1.258 amp

means i1 = 2.51 amp anticlockwise direction

i2 = -1.53 amp

|i2| = 1.53 Amp.
