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

Short Answer

For the circuit shown in the figure, the ideal battery has an emf ? = 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 heat is being generated in the resistor R₄.
