Electricity

Electric current is the flow

Electric current is the flow of electric charges through a conductor. It is measured as the amount of charge flowing through a cross-section per unit

Electric potential difference between two points

Electric potential difference between two points is the work done to move a unit charge from one point to another. Formula: V = W/Q, where V is potent

The potential difference across a conductor

The potential difference across a conductor is directly proportional to the current flowing through it, provided temperature remains constant. Formula

Resistance is the property of

Resistance is the property of a conductor that opposes current flow. It depends on length (R ∝ l), area of cross-section (R ∝ 1/A), and material. Form

In series combination

In series combination, resistors are connected end-to-end. Current remains same throughout (I = I₁ = I₂ = I₃), but voltage divides (V = V₁ + V₂ + V₃).
