HELP/// 19.0 Ω, 9.00 Ω, and 2.00 Ω resistors are connected in series with an emf source. The current in the 9.00 Ω resistor is measured to be 15.0 A. a) Calculate the equivalent resistance of the three resistors in the circuit.
Answer in units of Ω.
b) Find the potential difference across the emf source
Answer in units of V.
c) Find the current in the other resistors.
Answer in units of A.

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
