- Electricity is the most common form of energy used in the home. Different characteristics of electricity are measured using different quantities and units, including:
- Voltage, which measures the force of flow of electricity, or potential difference. Measured in Volts(V). Australia uses 240V mains electricity while countries like the United States and Taiwan uses 110V to prevent deaths caused by electrocution
- Current, which is a measure of the volume of the flow of the electricity. Measured in Amperes (I)
- Power, which is a measure of a rate of which electricity flows through an appliance or in other words, rate of electricity consumption. Measured in Watts (P)
This website will aim to cover the following:
