(13%) Problem 6: Consider the circuit in the following diagram, where the resistances are R,-0.45R, R2-4R, R3 0.65R, and R,-5R, where R-26 . The circuit is connected to a V-2.6 V source. Otheexpertta.c 33% Part (a) Input an expression for the equivalent resistance of the circuit in terms of R,, R2, R3, and R4. Grade Summary Deductions Potential 1 Submissions Atempts remaining % per attempt) detailed view Submit I give up Hints: 3 for a 0% deduction. Hints remaining: Feedback: deduction per feedback Resistors in parallel add by inverses. Resistors in series simply add Start by finding the equivalent resistance of the 3 in parallel. 33% Part (b) Input an expression using the Rey and V for power expended by the circuit. 33% Part (c) What is the power P, in watts?Explanation / Answer
a] Req = R4 + 1/[1/R1 + 1/R2 + 1/R3]
b] Power = V^2/Req
c] power = 2.6^2/[26*(5 + 1/(1/0.45 + 1/4 + 1/0.65))]
= 0.0495 W
