How long will a device drawing 8 mA last on a 12 v bat that has a 25mAh?
25/8 = 3.125 hours?
25/8 = 3.125 hours?
Voltage is electrical pressure, and it is analogous to water pressure. We don't need to know what the voltage is to answer this; we just need to know that it is considered consistent throughout the problem. The question should be stated as:How long will a device drawing 8 mA at a particular given voltage last on a battery that has a capacity of 25mAh at the same given voltage?.david90 said:How long will a device drawing 8 mA last on a 12 v bat that has a 25mAh?
Yes, if the question is stated as I corrected above.25/8 = 3.125 hours?
An amp, short for "amplifier," is an electronic device that increases the amplitude of an electrical signal, typically used to boost the volume of audio signals.
An amp works by taking an input signal and increasing its amplitude through a series of electronic components, such as transistors and capacitors. This amplified signal is then outputted to speakers or headphones.
There are several types of amps, including tube amps, solid-state amps, and digital amps. Tube amps use vacuum tubes to amplify signals, while solid-state amps use transistors. Digital amps use digital signal processing to amplify signals.
A preamp is responsible for receiving and amplifying the initial input signal, while a power amp takes that amplified signal and boosts it even further to drive speakers or headphones.
Yes, an amp can greatly affect the sound quality of an audio system. A high-quality amp can provide a clean and powerful sound, while a lower-quality amp may introduce distortion or muddiness to the sound.
