623 - What is voltage, and how does it affect electricity?

Voltage is like the 'pressure' of electricity in a circuit. Think of it like water in a hose:

• The water is like the electric current (the flow of electricity).
• The pressure of the water is like the voltage (the force that makes the electricity move).
• The hose is like the wire.

If the pressure (voltage) is high, the water (electricity) flows faster and stronger through the hose (wire). If the pressure (voltage) is low, the water (electricity) flows slower and weaker.

So, voltage affects electricity by controlling how fast and strong the electric current flows.
