Question

3) The currentin a circuitmade up of anetwork of resistors isgoverned by Kirchoff's Law. Kirchoff's voltage lawstates that the sum of the voltage drops around any closed loop inthe network must equal zero. rn 12 13 12 r4 Vi e1 ? r6 In the example above Kirchoffs Lawcan be applied and following set of equations are obtainedforthe firstand secondloop, respectively Solve the above equations forthe two unknown currents 1 and12 with R1- 10, R2 5, R3-20, R4 15, R5= 25, R6 : 10 ohms and V1 = 9 volts. 4) The resi stance of a metal follows the followingrelationship R=a+bT + cT Determine parametervalues, a, b, and c, usingthe followi ngthe two data sets T (K) R (Ohms) 15.0 21.1 36.0 00 400 600

Explanation / Answer

as per the chegg policy i solve question 3 only.

R1=10;R2=5;R3=20;R4=15;R5=25;R6=10;v=9;
A = [-R1-R3-R5 -R3
-R3 R3+R6+R4+R2];
b = [-v; 0;];
x = A;
%% x IS A MATRIX WHICH SHOWS THE VALUE OF CURRENT%%
