✨hii mate..✨

==============

here is ur answer ^↓^

====================

⭐⭐given that energy consumed by a bulb (1 bullb) is 500 W⭐⭐

Since,

1 kW = 1000 W

→ 1 W =1/1000 kW

so,
→500 W = (1/1000)×500 kW

→500 W = (500/1000)kW

→500 W =1/2 kW

→500 W = 0.5 kW

since,
we have to find it as kWh

energy consumed by a bulb in 1 hour

→energy × time
→0.5 kW × 1 hour
→0.5kWh

hence,energy consumed by 4 bulbs is ^↓^

→ 4 × energy consumed by 1 bulb

→ 4 × 0.5 kWh

→ 2.0 kWh

hence,
the energy consumed by four of them in kWh is 2 kWh..✔✔✔✔



=================
Alternate method ↓
=================
energy = 4 × 500 W
→ 2000 W

in kW
→ 2000 W = 2000/1000 kW
→ 2kW

in kWh
→2kW × 1 hour
→ 2kWh
