Direct vs Alternating Current

Because direct current always flows in the same direction, it transports mobile charges.

Because alternating current reverses, it just moves charges back and forth with no net change in position.

Implications --- Example: --- Question:

Both current and voltage reverse periodically so that a graph of either one versus time looks like this:

Implications --- Example: --- Question:

One cycle of alternating current is the shortest episode that repeats. The number of cycles per second is called the frequency.

Implications --- Example: --- Question:
