Section 1
• Amps • When compared to water in a pipe – amps is similar to flow (gallons per minute) • When water is flowing through a pipe, the pipe creates resistance to its flow. There will be pressure drop from one end of the pipe to the other. • Smaller/longer pipe will cause larger pressure drop from one end to the other. • The same applies to electricity in the form of wire. • Smaller/longer wire will cause a larger voltage drop from one end to the other. • Why understand amps is important during start-up and troubleshooting • Amps determine how hard a motor is working • A motor has a maximum amperage based on its HP rating • If a motor is drawing too many amps, it will overheat and eventually fail
