Answer:
Sensor/transducer: bimetallic thermometer
Output: displacement of thermometer tip
Control Tstages: mercury contact switch (open:furnace off; closed:furnace on
Explanation:
for a standard room thermostat
: This is the device that sets/determines the temperature of an enclosure.
Sensor/transducer: bimetallic thermometer: Bimetalic thermometer are used for measuring the temperature of the ambient air
. bimetallic thermometer actually contains two metals. they undergo linear expansivity as the temperature of the room changes.in other words, they experience contraction and expansion with increase or decrease in temperature.The sensor is basically coupled with a transducer which turns the measured variable(Temperature) into something else, such as a movement on a dial or an electrical signal
Output: displacement of thermometer tip
Controller: mercury contact switch (open:furnace off; closed:furnace on)
once the contact switch is open the furnace can go off. when the contact switch is closed, the furnace will come up.
Answer:
In terms of energy conversion/transformation the generator that produces 40 kilowatts of power will consume twice as much fuel than a generator that produces 20 watts because the more electrical power produced by an electrical generator, the more fuel is consumed. The amount of electrical energy produced is directly proportional to the fuel consumed.
Explanation:
Energy transformation is the conversion of energy from one form to another. Their are various forms of energy namely kinetic energy, electric energy, mechanical energy , chemical energy , solar energy, heat energy , nuclear energy. These energy can be transformed from one form to another . Example our body convert chemical energy through food we eat to mechanical energy.
The generator transforms mechanical energy into electrical energy . The kilowatts tells you the amount of power the generator produces .The energy is measured in kilowatts per hour which is the power used over a period of time.
In terms of energy conversion/transformation the generator that produces 40 kilowatts of power will consume twice as much fuel than a generator that produces 20 watts because the more electrical power produced by an electrical generator, the more fuel is consumed. The amount of electrical energy produced is directly proportional to the fuel consumed. So far the generator conversion efficiency are equal for both generators the generator with the higher power generation will consume more fuel per hour.
