Yes.
Increasing volume means the speakers have to work harder. Harder work means more output power. More output power can only be done by using more input power.
More input power can be done EITHER by increasing current, OR increasing voltage.
And the way most appliances and our distribution network is designed means that the voltage stays the same and the current is increased.

Why does the radio volume drop as a car speeds up?
The radio volume doesn't change - it is the other ambient noises associated with increasing speed (road noise, engine revs, other vehicles) that make it appear that the radio is getting softer. Some radio systems compensate for this automatically and lower the volume when decreasing speed and vice versa.
What do you mean by variable resistance or rheostat?
The volume control knob on a radio is an example of a variable resistor. By turning a knob, the resistance is altered and the volume (or current) is altered up or down.
A pocket transistor radio is in the playground. it is receiving radio 1 but the signal is weak and the radio output is quiet. when put against a metal down pipe the radio gets louder immediately why?
== == == == the metal pipe is inductively coupled with the antenna or the ground circuits by being so close. this effectively increases the antenna system. increasing the capture area gives a better signal. its a fairly common effect. often just holding a portable radio in your hand increases the signal
How do you fix radio volume on 89 Benz 300 e?
how to fix volume on radio the stations are there but no sound
Is amplification the act of tuning a radio to select a particular broadcast station?
Amplification is the process of making a signal louder. It is not the same as tuning a radio receiver. An amplifier is a device that takes a signal and makes it bigger as it reaches the amplifier's output. It can make the signal bigger by increasing the voltage, increasing the current or increasing both current and voltage, known as power amplifiers. Audio amplifiers that drive a loudspeaker are power amplifiers as they increase the power of the signal to drive the speaker itself. Tuning a radio adjusts the frequency that the radio aerial is sensitive to and allows only one frequency to be captured by the circuit attached to the aerial. By doing this, the radio can pick up a single broadcast and reject others. Before we can hear the received radio signal, it will be passed through a power amplifier and then to the speaker.
When you turn your radio up what increases?
frequency
What happens with the volume if the radio increases the double?
volume of any sphere = (4 / 3) * pi (a constant 3.14159) * radius cubedso if radius = say 2 cm, volume = 33.51so if radius = 4 cm, volume = 268.08so if you double the radius, you (2)^3= 8 times the volumeand if you treble the radius, you (3)^3 = 27 times the volume
How do you adjust the volume on a 2004 harley davidison radio?
You look on the left side of the radio and there is a knob.. That is a volume control....Turn it to the left for lower volume and to the right for higher volume... LOL
The factory radio volume on 323i BMW all of a sudden went mute How do you repair the factory radio volume when the display is lit however no volume on radio.?
well i think you are talking about a e46, 99 model year or newer, do you not have volume in any mode? radio, or cd/cassette, if that is the case then you might have defective radio, no repair is made, you will have to replace it.
Where is the vss on a 2002 Explorer XLT?
ford vss wire locationif the harness is similar to 02 ranger look behnd radio to the left there is a module the grey/black is the vss also if your vehicles radio volume automaticaly increases with the speed of your vehicle then the wire will also be located in your radio harness hope this helps>>>>> Jim t
In the potentiometer resistance increases gradually then why fan speed increases?
Hope this doesn't shock you ... the high-speed (or high-radio-volume) end of the potentiometercan very well be the low-resistance end. It's wired in such a way that as you turn the knob fromleft to right, the resistance decreases gradually.
When multiple radio telescopes are used for interferometry resolving power is most improved by increasing?
Increasing the distance between the two most widely separated radio telescopes has an enormous effect on resolution.
