Electrical systems for mobile, marine, and off-grid applications rely on fundamental units of measurement: watts, watt-hours, volts, ohms, amps, and amp-hours.0:12 Watts represent the total quantity of power required by a load, while watt-hours measure the rate at which that power is consumed, stored, or generated over time.0:45 Volts define the pressure pushing that power through a circuit, and ohms measure the resistance of the materials, such as copper wire, carrying the current.6:04 Amps indicate the flow of electricity, calculated by dividing wattage by voltage; this value determines the necessary wire gauge for a specific installation.9:01 Direct current (DC) typically powers 12-volt devices from batteries, while alternating current (AC) powers household appliances through an inverter.12:08 Understanding these core concepts and the distinction between VAC and VDC ratings is essential for designing electrical systems and performing accurate power audits.12:08
