Question

Przelicz energie podana w kilowatogodzinach na dzule
1kwh=.............J=..........kJ
20kwh=............J=....................MJ
0,36kwh+=.....................J=............kJ

Answer 1

1kWh = 1kW · 1h = 1000W · 3600s = 3 600 000J = 3 600kJ
20kWh = 20 ·3 600 000J = 72 000 000J = 72MJ
0,36kWh = 0,36 · 3 600 000J = 1 296 000J = 1 296kJ
