Aresistor is kept at a constant temperature while current flows through it. the potential difference across the resistor is kept constant. someone says: "current is used up as it moves through a resistor. since we know = then the resistance of the resistor can’t be constant". what mistake is being made? explain.

The human body stores chemical energy from digested food. some of the chemical energy is converted into mechanical energy when the body moves. which statement best supported by this information

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.
