Watt is a measure of power, while watt-hours is a measure of energy. This means you can pull 600 W, but not for an hour. You can pull 168 W for one hour. The watt rating gives you an idea of how much current you can draw through the device at any one time. The amp-hour or watt-hour rating will tell you how long before the battery is flat.

As you might remember from our article on Ohm''s law, the power P of an electrical device is equal to voltage V multiplied by current I:. P = V × I. As energy E is power P multiplied by time T, all we have to do …
There are three main methods for measuring power consumption for standby power or other similar applications. If the power value is stable, then the instantaneous instrument reading at any point in time can be used. If the power value isn''t stable, then take either an average of the instrument readings over time or measure total energy ...
DC Power Calculation. To calculate the power dissipated by each light bulb, we insert the measured values into the formula given above. If we want to know the power dissipated by the entire circuit, we add up the power dissipation of the individual components: Or, we can multiply the current supplied from the battery by the battery''s voltage:
As you might remember from our article on Ohm''s law, the power P of an electrical device is equal to voltage V multiplied by current I:. P = V × I. As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:. E = V × I × T. Hopefully, you remember that …
This ripple is due to incomplete suppression of the alternating waveform within the power supply. In AC to DC converters, AC voltage is apparent. But in DC-DC converters, we are switching the input DC. This results in the ripple being introduced. The below waveform shows the DC Supply and Ripple or AC Component in a AC-DC Supply.
Amp-Hour Application to Measure the Battery''s Capacity. A battery with a capacity of 1 amp-hour should be able to continuously supply current of 1 amp to a load for exactly 1 hour, or 2 amps for 1/2 hour, or 1/3 amp for 3 hours, etc., before becoming completely discharged. In an ideal battery, this relationship between continuous current and ...
