Study Notes

Electric Current Fundamentals

The unit of electric current is the ampere (A), which is defined as one coulomb per second.
The direction of conventional current is from positive to negative, opposite to the flow of electrons.

Voltage and Current Relationships

The relationship between voltage and current in a conductor is described by Ohm's Law, where current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R), I = V/R.
