Input an expression for the equivalent resistance of the

Question

Consider the circuit in the following diagram, where the resistances are R₁ = 0.15R, R₂ = 2R, R₃ = 0.75R, and R₄ = 5R, where R = 33 Ω. The circuit is connected to a V = 3.9 V source.

Part (a) Input an expression for the equivalent resistance of the circuit in terms of R₁, R₂, R₃, and R₄.

Part (b) Input an expression using the R_eq and V for power expended by the circuit.

Part (c) What is the power P, in watts?
