Obtain an expression for pe, the rate at which the battery is supplying electrical energy to the circuit. express your answer in terms of the variables e, r, l. pep e = request answer part i in terms of e, r, l, at what value of t is pe a maximum? what is that maximum value? in terms of , , , at what value of is a maximum? what is that maximum value? t=0 and pe=e2r t=0 and pe=2e2r t →[infinity] and pe= e2r t → [infinity] and pe=2e2r

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
