Question

IR1 =
Your response differs from the correct answerby 10% to 100%. mA IR2 =
Your response is within 10% of the correctvalue. This may be due to roundoff error, or you could have amistake in your calculation. Carry out all intermediate results toat least four-digit accuracy to minimize roundofferror. mA IR3 =

Explanation / Answer


(a)
   from the given circuit let us assume that the currentin both of the loops is in clockwise    direction
   the current in the left loop is i1 and inthe right loop is i2
   then using the kirchoffs mesh analysis we get
   70.4 – 61.9 - (3.0 x 103)(i1 - i2) - (2.0 x 103)i1 = 0 and
   61.9 - (4.0 x 103) (i2) –80.0 - (i2 - i1) (3.0 x 103) =0
   solve the above two equations for i1 andi2
    the current in the 2 k resistor willbe
   I2 k = i1
           = ......... amps
   I4 k =i2
           = ......... amps
   I3 k = i1-i2
               = ......... amps
(b)
    the required potential difference willbe
   V = (61.9 V) + [(I3 k)(R2)]
       = ......... V
