Answer 1

7.002 4:00h 9.00 R a) hits find the equivalent resistance between c and D. In this foor and R in parallel combination, If the equivalent resistance is r. Then, b ě - 3 + 5 - : k = 1347 - 20 Now, the circuit becomes, 9.002 R 9.00 1320 a b sig. d. Now, between a and b, 42,92 and R are in series. So, the equivalent resistance between a anda Rea = 4:00 & 9.oor & R' a 13.002+ 1347 20 - 17.552

6) The cunnent through the cincuit, I = 340 17.55 - 1.937 A making reference to sig, since, 42,92 and e are in series, the current I Hows through all these resistances. Now, consider the part of co. 72 I four since, the voltage between 72 and R (=132) are same. Using ohin's law, 132 V=IR ,on, I on, I & 1/2 - het, I, and I are currents through 72 and R (= 132) respectively, Then, using . 72 and c nn 12 and I t Iz = 1.937 21937 - I = 0.6779 A 2y and I = (1.937-06779) = 1.25905 A

I (4:002) - 10937 A I (7:002) = 1.25905 A I (13.00.2 2 0.6779 A I (9.000) = 1.937A
