Electricity: Voltage and Amperage

Study Notes

Electricity: Voltage and Amperage

Voltage is the force or pressure that pushes electricity through a device or a circuit.
A higher voltage means a stronger push, similar to how harder you push on a bicycle pedal, the faster it goes.
Amperage is the amount of electricity flowing through a circuit at any given time.
Imagine it as the number of "Lego pieces" of electricity flowing through the circuit.
Watts (power) is calculated by multiplying voltage and amperage (watts = volts x amps).
Higher amperage means more electricity is flowing through the circuit, similar to pushing more Lego pieces through the circuit.

Electrical Compatibility

The voltage of a device must match the voltage of the outlet it's plugged into.
For example, a device designed for 220-240 volts can't be used on a 110-volt outlet.
In the Philippines, standard voltage is 220-240 volts, while in the United States, it's 110-120 volts.
This difference in voltage influences the size and thickness of electrical wiring needed for homes and buildings.
Higher voltage requires thicker wiring to handle the stronger electrical push.

Understanding Kilowatt-Hours

Kilowatt-hour (kWh) is a unit of energy consumption.
It represents the amount of power used over a specific time.
One kilowatt-hour equals using 1000 watts for one hour.
Electricity bills often measure consumption in kilowatt-hours.
The electrical power needed for an appliance or device is measured in watts.
Example: A vacuum cleaner with 600 watts running for one hour consumes 600 watt-hours or 0.6 kilowatt-hours.

Power Banks and Milliamp-Hours

Power banks are often rated in milliamp-hours (mAh).
A 10,000mAh power bank can store enough electricity to power a device for a certain amount of time.
The power bank's capacity is the amount of energy it can store, similar to the amount of Lego pieces held in the power station.
Milliamp-hours (mAh) are a measure of electrical charge, while watts are a measure of power.

Greenfield Power Station

Greenfield's power station is a portable generator.
It can be used to power essential appliances like electric fans and modems during power outages.
The power station has a maximum output of 800 watts.
It can be charged using solar panels, wall outlets, or USB connections.

Summary

Voltage, amperage, and watts are crucial concepts for understanding electricity.
Voltage represents the force or pressure that pushes electricity, while amperage represents the amount of electricity flowing through a circuit.
Watts represent the rate at which energy is consumed or used, while kilowatt-hours measure total energy consumption over time.
Power banks store energy and release it to power devices when needed.
Greenfield's power station provides convenient power during outages.
