What Is Voltage?
Voltage is the electrical pressure that pushes current through a conductor. Without voltage, current cannot flow.
Current and voltage work together. Learn about current in What Is Electric Current?.
Water Pressure Analogy
Think of voltage as water pressure in a pipe.
Higher voltage → more push
Lower voltage → weaker push
No voltage → no flow
Voltage in Homes
In India, standard household voltage is 230V (single phase).
Larger buildings may receive 415V three-phase supply. Learn more in Single Phase vs Three Phase.
