no a watt is a measurement of electricity
It depends on the circuit that controls the siren. The circuit may be designed for only a 100 watt device and by doubling the current through the circuit, the circuit may be destroyed.
The formula you are looking for is Watts = Amps x Volts.
about 4800 watt but should not use it 100% so to be safe 4000 watt (80%)
Yes, if that is all that is on the circuit.
No, the current will be too high.
For a 1500 watt hot water heater connected to a 110 volt power source, you would need a 13.6 amp circuit. It is recommended to use a 15 amp circuit to provide some safety margin.
power/voltage=Amperage. If the circuit is rated above 33.4 Amps it can.
1 amp
The unit of power measured is watt, irrespective of resistance, capacitance or inductance of the circuit.
There are four watt-meters that indicates short circuit test. The four are method, procedure, calculations and fault.
The TBA820 is a 2 watt general purpose amplifier integrated circuit, not a resistor.
The standard unit of electric energy is the Watt Hour.
