What solid-state components in a mobile phone maintain proper voltage levels in the circuits?

transistors

diodes

microchips

capacitors

Diodes helps in maintaining proper voltage levels

Explanation:

Electronic components such as diodes allow current to flow in forward biasing.

Under reverse biasing diode does not allow current to flow but a negligible amount of current does flow.

Forward biasing allow current to flow after crossing potential barrier .

When crossing this potential barrier we can observe an increase in current but the voltage does not go higher than . Even with the high input voltage.

Hence, diode maintains proper voltage in circuits.

the answer is to check all of them! they all apply well at least i think so!

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
