After conducting research and analysis, it can be concluded that there are various reasons why shielding might not be fully utilized on electrical devices.

One reason is the cost involved in implementing shielding measures, which can be significant depending on the level of protection required.

Another reason is the space limitation within the device, as the addition of shielding could take up valuable space that can be used for other components.

Finally, lack of awareness about the importance of shielding in certain applications can also be a contributing factor.

In summary, the decision to fully utilize shielding on an electrical device depends on a variety of factors, including the cost, space limitations, and level of awareness about the benefits of shielding.
