For the Circuit Shown in the Figure, the Ideal Battery ε=80 V\varepsilon = 80 \mathrm {~V}

question 370

Short Answer

For the circuit shown in the figure, the ideal battery has an emf ε=80 V\varepsilon = 80 \mathrm {~V} . The four resistors have resistances of R1=14Ω,R2=21Ω,R3=21ΩR _ { 1 } = 14 \Omega , R _ { 2 } = 21 \Omega , R _ { 3 } = 21 \Omega , and R4=14ΩR _ { 4 } = 14 \Omega . Calculate the rate at which heat is being generated in the resistor R4R _ { 4 } .
