For the Circuit Shown in the Figure,the Ideal Battery Has $R 1 = 14 \Omega$

question 34

Short Answer

For the circuit shown in the figure,the ideal battery has an emf ε = 80 V.The four resistors have resistances of $R 1 = 14 \Omega$ $R _ { 2 } = 21 \Omega$ $R _ { 3 } = 21 \Omega$ and $R _ { 4 } = 14 \Omega$ Calculate the rate at which thermal energy is being generated in the resistor R₄.
