|
|
Term
| Electric Potential Equation |
|
Definition
V=U/q: where U is the electric potential energy and q is the test charge

|
Term
| How does a positive test charge spontaneously move? |
|
Definition
| Positive test charge moves from a high electric potential to a low potential which is negative work being done on the test charge leading to a decrease in the electric potential energy |
|
|
Term
| How does a negative test charge spontaneously move? |
|
Definition
| Negative test charge moves from a low electric potential to a high potential which is negative work being done on the test charge leading to a decreasing electric potential energy |
