Answer :
Answer:
the intensity is reduced
Explanation:
In electronic equipment, the volume is controlled by the power supplied to the speakers, the power is given by the formula
P = V I
In general, it is easier to control the voltage =, as important as this is a linear relationship, so by lowering the selector the controlled variables V or I decreases by half, so the intensity decreases at half.
In summary the intensity is reduced
Answer: the intensity is reduced.
Explanation:
The power is cut by half because the volume control works like a potentiometer. In an audio amplifier, the volume is controlled by the power supplied to the speakers, the power is calculated using
P = V I
Since V = I R
P = I (I R)
A potentiometer can be used to control the amount of voltage in a circuit by increasing or decreasing the resistors in a circuit. When the resistor is increased, power is reduced thereby lowering the volume and equally when the resistor is decreased, power is increased thereby raising the volume.
In summary the intensity is reduced
