Question

A circuit consisting of 5 resistors is shown in the graph. Their resistances are R₁ = 16 Ω, R₂ = 55 Ω, R₃ =83 Ω, R₄ = 29 Ω, and R₅ = 39 Ω, and the emf of the battery is µ = 5 V. Suppose the internal resistance of the battery is zero.

Express the equivalent resistance of the combination of R₂, R₃, and R₄.

Express the total resistance of the circuit R in terms of R₁, R₂, R₃, R₄, and R₅.

Calculate the numerical value of the total resistance R in Ω.

Express the current I through R₁ in terms of the emf A?µ and the equivalent resistance R.

Calculate the numerical value of I in A.

Express the power P dissipated by R₁ through I and R₁.

Calculate the numerical value of the power P in W.
