Abattery does work in moving charge around a circuit i. e. sustaining a current through the circuit. to illustrate this point, consider a resistor with a voltage v across it and a current i flowing through it. part a focus on a single charge, q, passing through the resistor. find the work w done on the charge by the electric field in the resistor. express the work w done on the charge in terms of q, v, and/or i.

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
