Question:
What are the properties of electricity? I know that light has wavelengths, but what differentiates one electrical pulse from another? Is it only voltage and whether it is AC or DC?

Replies:
Electrical pulses can be characterized by how their voltage and current change with time. Both voltage and current are signed quantities so they can be either positive or negative.
