Ohm’s Law

Ohm’s Law defines the relationship among three fundamental quantities: current , voltage , and resistance. It states that current is directlyproportional to voltage and inversely proportional to resistance. ELECTRIC CIRCUITS current flows from a point with an excess of electrons to a point with a deficiency of electrons. The path that the current follows is …

Resistance

Resistance is opposition to the flow of current . Some materials such as glass and rubber offer great opposition to current flow. Other materials such as silver and copper offer little opposition to current flow. The size and type of wires in an electrical circuit are chosen to keep the electrical resistance as low as …
