Voltage Explained

This video tutorial explains voltage, potential difference, and how they relate to electrical circuits. It uses a water pressure analogy to clarify these concepts and discusses the differences between direct and alternating voltage. The tutorial also covers how to measure voltage, the units used, and the global variations in voltage standards. Safety precautions are emphasized, and the historical context of voltage standardization is provided.

How do you measure voltage across a component in a circuit?

Explain the difference between direct voltage and alternating voltage.

Why do different countries have different standard voltages?

What could happen if a device rated for 110 volts is plugged into a 220-volt socket?
