Simple is just to know two formulas

Ohm's Law

V = IR

Power

P = IV

From those you can calculate voltage, amps, watts, ohms

V = Voltage (volts)

I = Current (amps or amperes)

R = Resistance (ohm's)

P = Power (watts)

Just solve for what you are missing.

Voltage times amps being drawn shows watts produced.

Watts divided by voltage shows amps being drawn or watts

divided by amperage shows voltage applied.

= = = = = = = = = = = = = = = = =

Power in watts (P) is voltage in volts (E) times current in amps(I).

P = E*I, E=P / I, I = P / E.

In a.c. that is peak to peak. To derive actual R.M.S. wattage (The true ability to do work)

you multiply peak to peak by 0.3535.

WattsI don't exactly know but this may help....if the amp has only 4 inputs (2negative, 2positive) then it will be 300w (around that mark)...if there is 4 negative and 4 positive for 4 speakers then it is likely to be around 1000w WRONG ANSWERThat is not even close. The best way to find out how many watts and amp is is to look at the specifications. If you know the make and model of the amp, look it up on the internet. The amount of "inputs" (which are really outputs) has nothing to do with the power. In fact, the most powerul amps have one channel.

Amps = Watts divided by Volts.

Volts = Watts divided by Amps.

Watts = Volts times Amps.

How many volts in a watt?

It depends on how many Amps (current) are applied to the voltage. Watt = Volts x Amps. e.g. 12 volts @ 5 amps = 60 watts


How do you convert watts into amperes?

To convert watts into amperes you divide the circuit voltage into the watts. Amps = Watts/Volts. <<>> Converting Watts to Amps The conversion of Watts to Amps is governed by the equation Amps = Watts/Volts For example 12 watts/12 volts = 1 amp Converting Amps to Watts The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts For example 1 amp * 110 volts = 110 watts Converting Watts to Volts The conversion of Watts to Volts is governed by the equation Volts = Watts/Amps For example 100 watts/10 amps = 10 volts Converting Volts to Watts The conversion of Volts to Watts is governed by the equation Watts = Amps x Volts For example 1.5 amps * 12 volts = 18 watts Converting Volts to Amps at fixed wattage The conversion of Volts to Amps is governed by the equations Amps = Watts/Volts For example 120 watts/110 volts = 1.09 amps Converting Amps to Volts at fixed wattage The conversion of Amps to Volts is governed by the equation Volts = Watts/Amps For Example, 48 watts / 12 Amps = 4 Volts Explanation Amps are how many electrons flow past a certain point per second. Volts is a measure of how much force that each electron is under. Think of water in a hose. A gallon a minute (think amps) just dribbles out if it is under low pressure (think low voltage). But if you restrict the end of the hose, letting the pressure build up, the water can have more power (like watts), even though it is still only one gallon a minute. In fact the power can grow enormous as the pressure builds, to the point that a water knife can cut a sheet of glass. In the same manner as the voltage is increased a small amount of current can turn into a lot of watts.


Single phase 220 volts 2.6 kW how many amps?

You cannot convert 2.6 kw to amps with that information only. In order to convert watts to amps, you also need to know either current or voltage. This is because watts is volts times amps, and volts is current times resistance


How many milliamps in 48.8 watts?

Milli amps is a measure of current whilst watt is a measure of power. The missing element is voltage as the formula is:- Power = Voltage * Amps ie power in Watts is the product of Volts (in Volts) times Amps (in Amps)


How many volts are 5000 watts?

Volts * Amps = Watts so since we don't know the voltage in the above equation: 1 volt * 50,000 Amps = 50,000 Watts OR 50,000 Volts * 1 Amp = 50,000 Watts Or 1,000 Volts * 50 Amps = 50,000 Watts Or The combinations are effectively infinite.

How many amps with 70 watts 13.8 Volts dc?

Watts = Volts * Amps Therefore: 70 Watts / 13.8 Volts = 5.07 Amps


4 volts is a many watts?

4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts... See Ohms Law: Watts = Volts x Amps If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts. If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.


How many volts it takes to cause a current of 1.95 amps to exist in a 200 watt lamp?

The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.


At 12 volts how many watts is 30 amps?

Watts is volts times amps, so 12 x 30 = 360 watts


How do you compute the 2000 watts in 220 volt to how many amps?

watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps


How many watts in 40 amps?

I t depends. Watts = Amps times volts. 40 amps x 120 volts =4800 watts or 40 Amps x 12 volts = 480 watts.


How many watt in amp?

It's watts divided by volts equals amps. Example: 1200 watts at 120 volts is 10 amps. To get the watts if you know the amps, multiply the amps times the volts. 10 amps at 120 volts is 1200 watts.


How many volts are there in 1367 watts?

volts times amps = watts


How many amperes in a watt and how many watts in a volt?

Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts


How many amps are produced by 10000 watts at 240 volts?

41.666 amps. Divide watts by volts.


How many watts of electric on a 13 amp fuse 240 volts?

You need the formula: Amps * Volts = Watts But you get to do the math.


How many amps is 6000 watts at 240 volts?

The equation that you are looking for is I = W/E. Amps = Watts/Volts.
