Question

find the energy in kWh consumed
im 10 hours by four devices of power. 500W each
find the energy​

Answer 1

Explanation:

Find the energy in kW h consumed in 10 hours by four devices of power 500 W each. Hence, the energy consumed by four equal rating devices in 10 h will be 4 — 5 kWh = 20 kWh = 20 Units.

Answer 2

Answer:

${\tt{\blue{\bold{\huge{Question}}}}}$

Find the energy in kw h consumed in 10 hours by four devices of power 500W each.

${\tt{\orange{\bold{\huge{Answer}}}}}$

Power rating of each device, P = 500 W = 0.50 kW

Time for which each device runs, t = 10 h

Work done = Energy consumed by each device (E)

We know, power = Energy consumed / Time

Energy consumed by each device= Power × Time

E = P x t

= 0.50×10 = 5 kWh

Hence, the energy consumed by four devices of power 500 W each in 10 h will be

4 × 5 kWh = 20 kWh = 20 units
