A desktop computer and monitor together draw about 0.6 A of current They plug into a wall outlet that is 120 V What is the resistance in ohms of the computermonitor combination?
To find the resistance in a circuit, use the equation R = V/I, where R is the resistence in ohms, V is the voltage, and I is the current in amps. Therefore, your equation is R = 120/0.6. Therefore, the resistance is 200 ohms. Hope this helps
The total resistance for this circuit if all resistors are 200 ohms is?
400 ohms
A series circuit has individual resistor values of 200 ohms 86 ohms 91 ohms 180 ohms and 150 ohms What is the total resistance of the circuit?
In a series circuits, you simply add the the values of each resistor and that is you answer. i.e. - 200 + 86 + 91 + 180 + 150 = 707 ohms
Can you play 8 ohm speakers on a 16 ohm amp?
There is no 8 ohm solid state amp. Really! The output impedance of such an amp will be arround 0.4 ohms. Scroll down to related links and look at "Interconnection of two units- Voltage Bridging - Zout < Zin".You can, as long as the amp's impedance is much lower to the speaker(s) total ohm load you're fine. We have never impedance matching there.
The voltage gran of an amplifier is 200 The decibel voltage gain is?
The voltage gain of an amplifier is 200. The decibel voltage gain is? Answer Gain in dB = 20 * log 200 = 46 dB
Can you run a 4 ohm speaker at 8 ohms?
No, it is not recommended to run a 4 ohm speaker at 8 ohms. Impedance mismatch can damage the amplifier or the speaker itself. It is always best to match the impedance of the speaker to the amplifier for optimal performance and to avoid potential damage.
How do you match speaker ohms to match a 4 ohm ampandHow many speakers can you add?
The amplifier will have an output impedance of around 0.04 ohms. We don't use matching. In hi-fi we have always impedance bridging. Zout
How many 4 ohms speaker is needed in 4 channel 8 ohms amplifier?
There are no 8 ohm amplifiers! All amplifiers will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout
If you have 8 ohm monitors rated at 95 watts rms and a 150 watt per side amp at 4 ohms Will this amp work for these speakers?
Strictly speaking, there are no 4 ohm amplifiers. An amplifier will have an output impedance of around 0.02 ohms. In hi-fi we have always impedance bridging. Zout << Zin. That means that the output impedance of the amplifier is much less than the impedance of the loud speaker. The damping factor Df = Zin / Zout tells you what Zout is. If the damping factor Df = 200 and the loudspeaker impedance is Zin = 4 ohms, the output impedance of the amplifier is Zout = 4 / 200 = 0.02 ohms. Scroll down to related links and look at "Voltage Bridging - Zout < Zin". Most amplifier manufacturers offer guidance on the minimum impedance speaker that can be used with the amplifier. Generally, an amplifier that is quoted at 150W at 4 ohms will be designed to run with a minimum impedance of 4 ohms on the output. An 8 ohm speaker will work without any problem at all but the output power will be rather lower than the 150W quoted for a 4 ohm load. The power rating of the speaker is an indication of the amount of power that the speaker can handle without distorting. If the speakers are being used as monitors with a fairly close listening position, it is unlikely that they will be driven close to their power limit.
Can i plug my 4 ohms Guitar amp into 16 ohms speakers?
That should be safe; although you won't get the best out of the loudspeakers. It's a myth. There is really no 16 Ohm amplifier on the market. And there never was. The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout << Zin. That means the output impedance of the amplifier is much less than the input impedance of the loud speaker. The damping factor Df = Zin / Zout tells you what Zout is. Zout = Zin/Df. If the damping factor Df = 200 and the loudspeaker impedance is Zin = 16 ohms, the output impedance of the amplifier is Zout = 16 / 200 = 0.08 ohms. You see, there is no "16 ohm amplifier" on the market with a 16 ohm output impedance. Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".
How can you hook up a 2 ohm amplifier to a 4 ohm sub?
The same as you would a 2ohm speaker. It's always OK to connect an amp to a speaker with more ohms than it's rated for but not less. Depending on the type of class of the amp the power produced at the speaker will probably be lower than rated spec but that won't harm the amp or the speaker. Turning it up until your ears bleed will. Something important is added: The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout
Can an 8 ohm speaker be driven safely by a 16 ohm Guitar amp?

Will a 4 ohm amp damage a 2 ohm speaker?
No, but it may be the other way around. Since you're using a 2 ohm speaker, don't expect the volume to be louder since the speaker uses twice as much power than a 4 ohm speaker does. If anything, I'd be cautious about the amp having the ability to handle the extra load. It's a myth. There is really no 4 Ohm amplifier on the market. And there never was. The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout << Zin.

Will 4 ohm speakers work with a 6 ohm amplifier?
It's a myth. There is really no 6 Ohm amplifier on the market. And there never was. The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout
Your speakers will handle 400 watts but start to disort at 200 watts?
The speaker impedance does not match the amplifier's specified speaker impedance.
Can you hook a 200 watt amplifier to a 120 watt sub woofer?
Yes it should be all right. Ratings for amp/speakers are approximate but as a rule it is preferable for the speaker to be rated higher than the amp.
Will 6 ohm surround sound speakers work with an 8 ohm amplifier?
