... This is an experimental law, valid for both alternating current (ac) and direct current (dc) circuits. When you pass an electric current (I) through a resistance (R) there will be a potential difference or voltage (V) created across the resistance. Ohm’s law gives a relationship between the voltage ...

... For electrostatic fields, the electric force is conservative (i.e. electric fields do not circulate). In this case, it is meaningful to talk about the change in the electrical potential energy of our test charge. From our work above, we see the change in the electrical potential energy per charge of ...
