FAQ:

Q: What is one ohm equal to in volts?

A: The SI derived unit for electric resistance is the ohm. 1 ohm is equal to 0.001 kiloohm , or 1 volt/ampere. Note that rounding errors may occur, so always check the results.

Q: How many volts are in 1 amp?

A: At 120V, 120 watts make 1 amp. That means that 1 amp = 120 watts. At 240V, 240 watts make 1 amp. Example 1: How Many Amps Is 500 Watts? Let’s say we have a 500W air conditioner plug into 120 V voltage.

Q: What is a stable amplifier?

A: A stable, compact, and inexpensive amplifier is described that permits using the Clark oxygen electrode to measure the oxygen consumption of even slowly respiring mammalian cells at the lowest cell densities at which exponential growth will take place.

Q: What is Mono car amplifier?

A: In most car and home audio applications, a mono amplifier is used to deliver power to a single channel speaker, such as a subwoofer. A mono amplifier is a single channel amp designed for low frequency sound reproduction, such as the deep bass produced by a subwoofer.
