Section 1
• Volts • When compared to water in a pipe – volts is similar to pressure • Electricity does not need to be flowing to have voltage • When a voltmeter is connected to a live circuit, it will read the voltage even if there is no active load (motor or lights) • Similar to a pressure gauge on a pipe
• Why understand volts is important during start-up and troubleshooting • Proper voltage is required for the unit to operate • Voltage that is too high or too low will cause damage or failure to components • Different types of voltages are used depending on the devices being operated
