Power is as easy as PIE (P=IxE). Watts equals the current squared time the resistance. Assuming a pure resistive load; they are equal. To answer the question precisely, one DC watt equals one AC watt.
Yes, watts is still volts times amps, for both ac and dc circuits. The complexity lies in the phase angle between voltage and current. If the circuit is purely resistive, the phase angle will be zero. If the circuit is capacitive or inductive, the the phase angle will vary, depending on frequency and on how much capacitive or inductive reactance there is. The difference comes into play when you consider true versus apparent power.
One of the cheapest ways to convert AC to DC voltage is to use a simple rectifier circuit made with diodes. This circuit allows current to flow in only one direction, effectively converting AC to pulsating DC. However, for smoother DC output, you may need to add a filter capacitor to the circuit.
While you can't exactly compare the two, the equivalent voltages, currents and powers can worked using the idea of RMS (which is the equivalent value in AC); this is the value which is given for just about everything you plug in: microwaves, toasters, shavers... Just calculate "DC x square root of half = equivalent value of AC". The opposite is "AC x square root of two = DC". For example, 240 Volts (normal home voltage) AC x sqrt 2 = about 340 Volts DC or 6mA DC (the amount needed to stop a human heart) x sqrt 0.5 = 4.2 mA AC.
12 V DC, 18 VA (watts) how many amps? Formula: amperage I = power P (VA) divided by voltage V. So, amperage I = 18 watts / 12 volts = 0.083 amperes.
To calculate the amperage, we can use the formula: Amps = Watts / Volts. In this case, it would be 70 watts / 13.8 volts ≈ 5.07 amps. So, with 70 watts and a voltage of 13.8 volts DC, the amperage would be approximately 5.07 amps.

how much energy is lost in converting dc energy to ac energy
Halfwave or fullwave or polyphase AC to DC?
A rectifier
Because, the commutator segments are used for converting AC to DC.
Output in watts.
how much energy is lost in converting dc energy to ac energy
Ac x 1.4 -1.4=dc
Alternating Current ... like in most households.The adapter is either converting DC to AC or vice versa.
Yes, by using a dynamo (which produces d.c.) instead of an alternator.
A: It not size but rather capacity. the capacity will be the ac power consumption AC volts X AC current that will get Watts. So the capacity of the inverter should be the same watts plus a safety and efficiency power if the watts is 100 watts i would buy a 125 watts minimum
