Electricity

Voltage, current, and resistance are related to electrical charge:
Voltage: The difference in charge between two points. Voltage is measured in volts (V).
Current: The rate at which charge flows. Current is measured in amperes (A).
Resistance: A material's tendency to resist the flow of charge. Resistance is measured in ohms (Ω).

Voltage: The electrical potential difference between two points.
Current: The flow of electrons in a circuit
.
Resistance: Something that resists the flow of electrons.

The relationship between voltage, current, and resistance is Ohm's Law
, which is represented by the formula V = R × I.
