Which of the following best describes the function of an inverter in firefighting equipment?

The function of an inverter in firefighting equipment is primarily to convert direct current (DC) into alternating current (AC). This is crucial in situations where equipment that runs on AC power is needed but only a DC battery source is available, such as in portable power systems used by firefighters in the field. The inverter allows for the operation of standard AC-powered devices, such as lights or tools, making it highly valuable in emergency scenarios where reliable power supply is essential. Therefore, understanding the role of an inverter is fundamental for firefighters, as it enables them to efficiently utilize available energy sources to power their equipment.
