find the energy in units consumed in the month of June by four devices of power 500 Watt each working for 10hrs daily.
Answers
Answer:
A WAN differs from a LAN because it is not restricted by geographic location. As opposed to a LAN which connects local devices to each other, a WAN connects LANs to each other, usually across multiple locations as well as individual devices that connect from a remote distance
Energy consumed by an electric device can be obtained with the help of the expression for power,
P = W/T
Where,
Power rating of the device, P= 500 W = 0.50 kW
Time for which the device runs, T= 10 h
Work done = Energy consumed by the device
Therefore, energy consumed = Power —Time
= 0.50 — 10 = 5 kWh
Hence, the energy consumed by four equal rating devices in 10 h will be 4 — 5 kWh = 20 kWh = 20 Units.
