(10%) Problem 4: A circuit consisting of 5 resistors is shown in the graph. Their resistances are RI-15 , R2-95 , R,-98 , R4-63 , and R5-29 , and the emf of the battery is E 6.5 V. Suppose the internal resistance of the battery is zero Otheexpertta.com 14% Part (a) Express the equivalent resistance of the combination of R2, R3, and R4 Grade Summary Deductions Potential 0% 100% Submissions Attempts remaining: 7 12 3 % per attempt) detailed view In 0 Submit Hint I give up!

a] Req = 1/[1/R2 +1/R3 + 1/R4 ] because they are in parallel
b] R = R1 + R5 + 1/[1/R2 +1/R3 + 1/R4 ]
c] R = 15+29+ 1/[1/95+1/98+1/63] = 71.3 ohm
d] I = E/R
e] I = 6.5/71.3 = 0.09116 A
f] P = I^2*R1
g] P = 0.09116^2*71.3 = 0.5925 W
