Final answer:
Most Apple mobile devices use a Lightning connector, while newer MacBooks and some iPads use USB-C connectors, to conduct electricity from power adapters to charge the devices.
Step-by-step explanation:
As of the current lineup, most portable Apple products like the iPhone, iPad, and AirPods use a Lightning connector for charging and data transfer. However, many of the newer models of Apple's MacBook and some iPad models have transitioned to using USB-C connectors. Both types of connectors allow electricity to be conducted from a power adapter or wall socket to the device to recharge the battery. The power adapters typically use metal wires and connectors to conduct electricity, with the metal providing a path for electrons to move. These wires are then insulated with materials like rubber and plastic to ensure safety and prevent electrical charge from escaping
