Final answer:
The statement is true; printed circuits are commonly used in vehicle instrument panels as well as in various other complex electronics like computers and cell phones.
Step-by-step explanation:
The statement that printed circuits are most often used in instrument panels of vehicles is true. Printed circuit boards (PCBs) are integral to modern electronics and play a vital role in automotive instrument panels, where they serve as the backbone for gauges, indicators, and control lights. In vehicles, PCBs are designed to withstand the rigorous conditions of the automotive environment and are used to facilitate both the monitoring and operation of the vehicle's functions.
In more general electronics, electric circuits, including those in computers and cell phones, vary widely in complexity and size, from basic circuits in everyday devices to highly complex arrangements within supercomputers. Specific to the automobile industry, printed circuits in instrument panels connect various electronic components to provide drivers with essential information and controls for driving.
