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
There are four watt-meters that indicates short circuit test. The four are method, procedure, calculations and fault.
The unit of power measured is watt, irrespective of resistance, capacitance or inductance of the circuit.
The TBA820 is a 2 watt general purpose amplifier integrated circuit, not a resistor.
The standard unit of electric energy is the Watt Hour.
