electrical energy is dissipated by at a rate of 36 W
Part A
Part complete
If a second resistor with R 2 = 11 ? is connected in series with R 1 , what is the total rate at which
electrical energy is dissipated by the two resistors?
Exercise 26.3 Part A lf a second resistor with R2-11 ? is connected in series with R1, what is the
total rate at which electrical energy is dissipated by the two resistors? Express your answer using
two significant figures. Constants A resistor with R1-23 2 is connected to a battery that has
negligible internal resistance and electrical energy is dissipated by at a rate of 36 W
Solution
let the voltage of the battery is V
part A )
Power = V^2/R1
36 = V^2/23
V = 28.8 V
net resistance , R = 23 + 11 = 34 Ohm
total rate of dissipation = V^2/R
total rate of dissipation = 28.8^2/34
total rate of dissipation = 24.4 W
the total rate of dissipation is 24.4 W
