-- If the 3 Amp is being drawn from a battery,

then the battery is supplying

3 x (Voltage of the battery) watts.

-- If the 3 Amp is flowing through a resistor,

then the resistor is dissipating

9 x (Resistance of the resistor) watts.

Q: How much power is consumed through a 3 amp?

That depends on the power ratings of the subs.

1 watt = 1 amp * 1 volt So.... In a house: 5 amps * 115 volts = 575 watts In a car: 5 amps * 12 volts = 60 watts

Yes. The "275W" is the maximum power that the speaker can handle at its input. The "120W" is the maximum undistorted power that the amp can deliver in the loud spots with the volume wide open. So the amplifier will never overdrive the speaker. The impedances of the speaker and amp-output should match. If one of them is marked "4 ohms", then they both should be. If they're not the same, then . . . -- the speaker may not sound as 'crisp' as it should. -- the amplifier may not deliver as much undistorted power as it should. -- the amplifier may not run as cool as it should. -- with an extreme mismatch and extended loud spots played at high volume, the amplifier may even be damaged.

Yes you can depending on the wattage of the amp. i personally would only put two 12's on one amp. cause it will still bump hard!!(:

"milli" means a thousandth in the metric units of measurement. Thus 1000 milliamps = 1 amp.

120 power flows through a circuit with 1 amp and 120 volts.

As many as you want. It is the power consumed by the thing(s) plugged in that is of concern.

your amp will ground in your sound system, or through your power adder which rock.

i would check you have a good ground the amp will still power up but no power will be put through the system if the ground is not good

Yes, but don't try to put 15 amps through it! You might need to change your plug too!

I had th same problem i had to turn my amp down i guess it was to much power out put

Volt-Amp (VA) is a unit of measurement for apparent power in an electrical circuit, representing the total power consumed by a device. It is the product of voltage (in volts) and current (in amperes) in an AC circuit. VA is important for sizing power supply equipment to meet the demands of the electrical load in a system.

No. The amperage describes the total electrical energyeither produced or consumed. Voltage just describes the potential. If the power cable or power supply are only capable of 1 amp and the device consumes 2 amps... sorry, you don't have enough electrical energy available.

No, amplituted is how much power flows in your amp. My tiny practice amp witch is 15 amps, (or so) and my friends monster amp can play at the same volume

OK. First, note that your heater doesn't 'generate' power. If it did, you could sell the power. Your heater consumes power. The electric company generates it, and you pay them for it. The power consumed on a household circuit is nominally (Voltage) multiplied by (Current). The voltage delivered to your house is nominally 117 volts AC, although it can vary by a bit. If the current through the heater is exactly 5 Amp, then the power is (117 x 5) = 585 watts, or 0.585 KW.

real P= V * I *cos(phase angle between V and I)for purely resistive loads or DC voltages this equals real power P=V*I = 120*5= 600Wattsfor not pure resistive loads you'd have to measure the phase angle between Voltage and Current to get real power.However, at home, the utility company charges for Complex power = V*I.So you'd still pay for V*I.
