Watts is the product of Amps x Volts, so you can see without any amps flowing watt equals zero.
A: A photocell is like a variable resistor it will change resistance with light the ratio of dark:light resistance decides the output. So yes it should work with 9volts
I believe its only 9volts, because if the power goes out that 9 volt battery will still keep the alarm activated.
Ignition 30 watts, fans 30 watts, driving lights 30 watts, headlights 100 watts. Total about 200 watts.
2,000 kw is 2,000 kilo watts is 2,000,000 watts
Use 100 watts
1400 watts.
its 1200 watts
! kw = 1000 watts 7800 kw = 7800 x 1000 watts = 7800 000 watts
It is 2400 million watts.
100 watt
Watts = Amps X Volts Grab your calculator!
There are 3.75 kW in 3750 watts. To convert watts to kilowatts, you divide by 1000.
