1 kWh = ?
RRB Group D / RRB ALP & Technician
RRB Group D / RRB ALP & Technician
2018
✓ Answer:C3.6 × 10⁶ J
1 kWh = 1000 W × 3600 s = 3.6 × 10⁶ J.
17
1 kilowatt is equal to?
RRB Group D
2019
✓ Answer:D1000 watt
A kilowatt is equal to 1000 watts.
18
1 KW = ?
RRB Group D
2018
✓ Answer:A1000 J s⁻¹
1 kW = 1000 W and 1 W = 1 J/s, hence 1 kW = 1000 J s⁻¹.
