Direction: Right-Hand Rule #1
This rule is based on the right-hand rule
for the cross product.
Your thumb is in the direction of the
force if q is positive.
The force is in the opposite direction of
your thumb if q is negative.

Current and Resistance
Electric Current
Electric current is the rate of flow of charge through some region of space.
The SI unit of current is the ampere (A).
1A=1C/s
The symbol for electric current is I.
