Question

     

at the right determine the values of i1, i2 and i3. Input your answers in the form "a.bc times 10^(y) A". Using the correct results from Quiz #4, determine the following. For A and B you must also tell if the current directions shown are correct. Give your answer in the requested format. The current in the 10.0 Ohm resistor. Answer format: "abc mA, Y/N". Y/N means choose Y if the current is as shown, and choose N if the direction of the current is not correct. The current in the 4.5 V battery. Answer format: "abc mA, Y/N". Y/N means choose Y if the current is as shown, and choose N if the direction of the current is not correct. The voltage across the 15.0 Ohm resistor. Answer format: "ab.c V". How mu Ch power is dissipated in the 5.0 Ohm resistor? Answer Format: "abc mW"

Explanation / Answer

let the current in the upper sectin be a, in the middle section be b and in the lower section be c.so,

writing the equations,

a+b=c

6+10a-9-20b-15b=0

20b+15b+5c+12c+4.5=0

a=-1.345*10^-3 A

b=-0.0861 A

c=-0.08744 A

so the directions given here are wrong in every case

A)1.345*10^-3 A

B)8.744*10^-2 A

C)V+ir

=1.2915 V

D)power=i^2r

=38.22 mW
