Question

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

Answer 1

Answer:

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 $0.65\ V$.

When crossing this potential barrier we can observe an increase in current but the voltage does not go higher than $0.65\ V$. Even with the high input voltage.

Hence, diode maintains proper voltage in circuits.
