Homework Answers
C. While moving from high voltage to low voltage battery does a work equal to charge of electron × voltage difference at the two end of the wire created by the battery. This is the energy taken from the battery. This is work done by the electric field created in the wire by the battery.
D. As the current flows through the resistor an amount of heat is generated due to the collision between the electrons and the atoms of the resistor. This equals the voltage of battery multipleid by current through the resistor multiplied the time passed. Due to this reason potential energy of battery get reduced.

Kirchhoft s law says that if you trace a path around any c age sources less the sum of the voltage drops must equal zero. Keeping in mind Ohm s Law, V IR, for the simple RC circuit shown in Figure 1 on the previous page where the power supply is hooked the capacitor is charging, Kirchhoff s law would say that aw says that if you trace a path around any closed-loop within a circuit, the sum of the...
