Question

16 bulb of 40 what are used for 6 hours a day along with 100 watt bulb for 2 hours calculate the unit of energy consumed in 1 days by all bikes

Answer 1

16 bulbs each of 40 W makes total of 16 × 40 = 640 W

So, in 6 hrs the energy consumed is = 640 × 60 × 60 × 6 J

The energy consumed in kWh is = (640 × 60 × 60 × 6)/(3600000) = 3.84 kWh

A 100 W bulb for 2 hrs will consume energy in kWh

= (100 × 60 × 60 × 2)/(3600000) = 0.2 kWh

So, net energy consumed = 3.84 + 0.2 = 4.04 kWh

In terms of ‘units’ it is 4.04 units of energy consumed per day.

Answer 2

Answer: 4.04 units

Explanation:16 bulbs each of 40 W makes total of 16 × 40 = 640 W

So, in 6 hrs the energy consumed is = 640 × 60 × 60 × 6 J

The energy consumed in kWh is = (640 × 60 × 60 × 6)/(3600000) = 3.84 kWh

A 100 W bulb for 2 hrs will consume energy in kWh

= (100 × 60 × 60 × 2)/(3600000) = 0.2 kWh

So, net energy consumed = 3.84 + 0.2 = 4.04 kWh

In terms of ‘units’ it is 4.04 units of energy consumed per day.
