That depend on the current rating of the cor in amps. The watt rating is equal to the voltage (300) times the current rating, which might be marked on the cord but anyway it depends on how thick the wire is.
A rolled-up power cord must ways be completely unrolled if more than one-tenth of the rated current is to be drawn. That is to allow the heat generated in the wire's resistance to escape.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
Since watts and volt-amps are different units of power, you cannot directly convert watts to volt-amps without considering the power factor of the load. In an ideal resistive circuit, 100 watts would be equivalent to 100 volt-amps. However, in practical applications with reactive components, the relationship between watts and volt-amps can vary.
Power (in watts) is calculated by multiplying voltage (in volts) by current (in amperes). So the power of 1 volt would need additional information about the current flowing through the circuit to determine the wattage.
The power required is(6) times (the amperes of current the radio draws when it operates) watts.
A 22VA transformer has a power rating of 22 watts. VA (volt-ampere) is a unit used to measure the apparent power in an electrical circuit.
how many watts aew needed to power a 110 volt tv at 1.30 amp
This is like saying how many marbles are in the jar. Watts = Volts x Amps x Power Factor.
770 watts.
The rated voltage of an appliance is no guide to its power rating. To find out the power (watts), you will need to look at your washing machine's nameplate, which will indicate both its rated voltage and its rated power.
It depends entirely on the power factor of the load. If the power factor is unity (1), then the true power, in watts, will equal the apparent power in volt amperes. If the power factor is zero, then the true power, in watts, will be zero. This is because true power (watts) is equal to the apparent power (volt amperes) multiplied by the power factor.
Assuming 100% efficiency, a 36-volt battery charger would use 36 watts per hour to charge the battery fully. However, it's important to consider that chargers are not 100% efficient and may draw slightly more power from the wall.
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
