a.Khối lượng nước tronh ấm là 
 Mn=V×D=3.1=3(kg)
Nhiệt lượng cần để đun sôi là:
Q1=Mn Cn ×(t2-t1)=3×4200×(100-25)= 945000(J)
Hiệu xuất của bếp là:H=0,80
Nhiệt lượng mà bếp tỏa ra là:
 Q2=Q1÷H=945000÷0,80=1181250(J)
Thời gian đun sôi nước là:
t=Q÷P=1181250÷1000=1181,25(s)=18 (phút)
b.Số kWh điện tiêu thụ trong 1 ngày dùng cho việc đun 3 lít nước là:
A1=3÷2×1181,25=177,375(J)=0,2(kWh)
Số tiền điện trả trong 1 tháng cho việc đun nước là:
30A1×900=30×0,2×900=5400(đồng)
Bài 2 
Công thức tính công xuất P=U2÷Rd->Rd=U2÷P=220mũ 2÷30=1613,3 ôm 
Vì điện trở R tính công thức : P=U2÷Rd=110 mũ 2÷1613,3=7,5W
