How do you calculate the watts of LED and energy saver lamp?
To calculate watts you need two of the three: Voltage (V), Current (A) and Resistance (ohm). Power (Watts) = (V^2) / R = (I^2)R = VI
Ow do you calculate amperage with watts and volts?
Divide...
How do you calculate the watts of a central air and heat unit?
You should not have to calculate the watts of the unit. All the information that you need will be on the nameplate of the unit. It is this information that electricians use to calculate the conductor size and breaker to supply the power to the unit.
How do you calculate watts from 7.5 HP and 208 voltage 3 phase?
Try 746 watts = 1 HP
How many volts in 12 mega watts?
Watts = Volts x Amps. 12 megawatts = 12,000,000 watts. You need to know current to calculate the voltage.
Claculate amps from voltage and watts?
calculate amp usage
How can you calculate the current an appliance can use?
current=watts(power)/voltage
How do you calculate power?
Power=work over time = watts(W)
How do you calculate power dissipated by an IC?
It is very critical to never exceed the input voltage of an IC to begin with. To calculate the power dissipation ( in watts) VxI (Voltage x Current) will give you power in watts.
Calculate the power in watts used if you exert 50 joules of work in 5 seconds?
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
How many watts are in 19.5 volts?
Impossible to know. You need to know both the voltage and current draw to calculate power (watts). Power in watts = Volts X Amps
