Q. 1 (a) Req= ( R2R3R4) / ( R2R3+ R3R4+ R2R4)= ( 25x 92x 46) /( 25 x 92 + 92x 46 + 46x 25) = ( 105800) / ( 2300 + 4232 + 1150 ) =105800 / 7682= 13.77 ohms
b) Total resistance= R1 + ( R2R3R4) / ( R2R3+ R3R4+ R2R4) + R5
c) R = 19 + 13.77 + 33= 65.77 ohms apprx
d) I = E / R1 + ( R2R3R4) / ( R2R3+ R3R4+ R2R4) + R5
e) I = 2.5/ 65.77= 0.038 A apprx
f) P ( through R1) = I^2 ( R1)
g) P = 0.038^2 ( 19 ) = 0.0274 watts apprx
