Given power info on a CRT monitor, how can I calculate power consumption (kWh)?
- by r0ca
I have a Dell CRT Screen and the only info I have is this:
AC input
voltage: 90 to 264 VAC
frequency: 50 or 60 Hz + 3Hz
current: 1.5A max. (RMS) at 120 VAC; or 0.8A max. (RMS) at 220 VAC
How can I calculate the energy consumption in Watt-hours for an hour (or better, a day)?
