Ohm's Law

Circuit Analysis V = IR

Conventional Current (+ to -)

V = I · R

V(Voltage): Unit Volts (V). It is the 'pressure' pushing charges.

I(Current): Unit Amps (A). It is the speed or flow rate of charges.

R(Resistance): Unit Ohms (Ω). It is the degree of opposition to flow.

Relationships

Directly Proportional
Increase Voltage -> Current Increases (Directly Proportional)
Inversely Proportional
Increase Resistance -> Current Decreases (Inversely Proportional)
