use a table like this to calculate the electrical usage over 5 days. Please use the table And make all calculations for each on a spreadsheet.

Please make a chart like below and record what u used and fill out the chart.

1. To obtain the amount of electrical energy used by an appliance you will need its power rating. (It can often be found near where the power cord enters the appliance, but see below for other options.) Multiply the appliance's power rating by the amount of time for which it was used. Conversion of the power rating to kilowatts (103 W') at this stage will enable you to easily obtain the energy use in kilowatt-hours (kWh). For example, for a 60 'N (20.06 kW] lightbulb that is left on for 3 hours, the energy used is 3 hours x 0.06 k\"" = 0.18 kWh (l) of energy. Sometimes the power rating isn't directly provided on the appliance, but the elec- trical current drawn by the appliance (in Amperes). together with the voltage (in Volts] at which it is drawn, is given. The power rating in Watts (\\N) can be estimated by multiplying both of these numbers together. For example, consider a AC to DC power adapter (eg. for a game console) which takes in 0.6 Amps at 120 V. Its power draw is 0.6 A x 120 V : 72 w (2) 4. As an example, a table of your electricity use might look like this (you should use a spread- sheet to record, calculate, and add up your electricity usage, and make sure that units are consistent before adding up): Date Appliance Power Rating (W) Time Used (hours) Energy Used (kWh) Jan 22 Desk Lamp 100 W 2.5 hours 0.250 kWh Jan 22 Computer (desktop) 55 W 2 hours 0.110 kWh Jan 22 Phone Charger 0.26 W 24 hours 0.00624 kWh (unplugged) (STANDBY) Keep track of standby power separately from the rest for clarity, and maintain separate totals. At the end of the five days, add up all of the energy consumed to obtain your total electricity consumption for the week
