Voltage Explained: The Push Behind Electric Current

Voltage is the electric “pressure” that pushes electrons through a circuit.
It’s measured in volts (V), named after scientist Alessandro Volta.
Without voltage, electrons have no reason to move, so no current flows.
A battery provides voltage by using chemical reactions to create an energy difference.
Power outlets supply much higher voltage than batteries, making them more dangerous.
Voltage is like water pressure—higher pressure means a stronger push.
High-voltage lines transmit electricity long distances with less energy loss.
Low-voltage systems, like phone chargers, are safer for everyday use.
Voltage differences between two points create the flow of current.
From tiny circuits in watches to lightning bolts in the sky, voltage drives it all.
