Questions answered in undefined manuals
How do you calculate electricity consumption for an appliance?
Multiply the appliance's power (in watts) by the usage time (in hours) to get energy consumption in watt‑hours.
How is standby (待電) power accounted for?
Add the standby power multiplied by the standby hours to the active consumption to obtain total daily energy use.
How is electricity consumption calculated?
It is calculated by multiplying the appliance's power (in watts) by the time it is used (in hours).
How do you account for standby power in the total consumption?
Add the standby power (待電) multiplied by the standby time to the active consumption.
