IEEE 802.15.4 is a technical standard which defines the operation of low-rate wireless personal area networks (LR-WPANs). It specifies the physical layer and media access control for LR-WPANs, and is maintained by the IEEE 802.15 working group, which defined the standard in 2003.[1] It is the basis for the ZigBee,[2] ISA100.11a,[3] WirelessHART, MiWi, SNAP, and Thread specifications, each of which further extends the standard by developing the upper layers which are not defined in IEEE 802.15.4. Alternatively, it can be used with 6LoWPAN, the technology used to deliver the IPv6 version of the Internet Protocol (IP) over WPANs, to define the upper layers.

Explanation:
When the potential difference across the two ends of the electrical component becomes half its former value, the current through it also becomes half. Since I = V/R, when potential difference becomes V/2, current becomes I/2 as the resistance (R) of the component remain' constant
