Question

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

Answer 1

Answer:

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.

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

Energy consumed by an electrical device will be obtained with the assistance of the expression for power,

P = T

Where,

Power rating of the device,

P = five hundred W = 0.50 power unit Time that the device runs,

T= ten h Work d consumed by the device thus, energy c × Time

= 0.50 × 10 = 5 kWh

Hence, the energy consumed by four equal rating devices in

10 h = 4 × 5 kWh = 20 kWh = 20 Units.
