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

Physics
1 answer:
grandymaker [24]3 years ago
3 0

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.

How does the voltage applied to the electric motor affect the coil's number of rotations and its rotational direction
sleet_krkn [62]
Higher voltage means faster rotation.  Changing the voltage polarity changes the direction of the motor.

Read the following and identify the main parts of the experiment.
slava [35]

The independent variable refers to the type of socks (synthetic socks), the dependent variable is the number of blisters and the control is the two weeks that she switches back to the cotton socks.

<h3>What is the dependent variable?</h3>

In an experiment, the dependent variable is those being tested and changes according to the independent variable.

The control group is the set of experimental conditions that is used to compare a given outcome in an experiment.

In conclusion, The independent variable refers to the type of socks (synthetic socks), the dependent variable is the number of blisters and the control is the two weeks that she switches back to the cotton socks.

A force of 14 lb is required to hold a spring stretched 4 in. beyond its natural length. How much work W is done in stretching i
enyata [817]

Answer:

W = 19.8 J

Explanation:

14 lb force is required to stretch the spring by 4 inch distance

So we have

F = 14 lbf

F = 6.35 \times 9.8 N

F = 62.3 N

stretch in the spring is given as

x = 4 in = 0.1016 m

now we will have

F = kx

62.3 = k(0.1016)

k = 613.125 N/m

Now we need to find the work to stretch it by x = 10 in = 0.254 m

so we have

W = \frac{1}{2}kx^2

W = \frac{1}{2}(613.125)(0.254)^2

W = 19.8 J
