Study Notes
Voltage and Amperage
- Voltage is the pressure that pushes electric current through a wire.
- Voltage is measured in volts.
- Amp, short for ampere, measures the strength of an electric current.
Power and Watts
- Watts represent a measure of power.
- The formula for calculating watts is: Amps x Volts.
- Watts indicate the rate at which energy or power is released or used.
Energy Production
- In the context of a water wheel, watts analogously represent the power produced from the flow of water.
- Watts measure the rate of production or use of energy.
Frequency and Hertz
- Hertz denotes the rate of change in the directional flow of electricity.
- A metaphor for hertz involves the natural ebb and flow of water at a shoreline, changing direction back and forth.
- The frequency of change in direction is measured per second and is expressed in hertz.
- 60 Hz indicates that the rate of change of directional flow of electricity occurs 60 times per second.
Geographic Influence on Frequency
- Geographic location affects electrical frequency standards.
- In the United States, the standard frequency is 60 Hz.
Applications of Hertz
- Equipment with alternating-current (AC) motors or timer controls relies on frequency (hertz) to determine motor speed and time.
- If a device designed for 60 Hz is plugged into a 50 Hz outlet, it may operate slower or inaccurately, resulting in running late.
