Xiao Ming helps his parents to budget the electricity bill in November. The following table shows the readings of the electricity meter every morning for 8 consecutive days in early November: 1,21,2,24,3,28,4,33,5,39,6,42,7,46,8,49. If the electricity bill per kilowatt hour is 0.53 yuan, what is the estimated electricity bill of Xiao Ming's family in November (30 days)?

The first day is the basic number, the other seven days 28 degrees walk, an average of 4 degrees a day, 120 degrees a month
120 times 0.53 yuan

An electric energy meter is marked with 600r / kWh. How much J of electric energy is consumed for 5 turns
Calculate the calculation process, calculate the conversion between kilowatts and joules. If one revolution consumes 1 / 600 kwh of electric energy, how much J is that? How to calculate?

Kilowatt is the unit of electric power. Joule is the unit of electric energy. Kilowatt hour is the unit of electric energy
W=5/600KWh=1/120KWh
1KWh=3,6×106J
So w = 1 / 120kwh = 3 × 104j

One degree of electricity in an electric meter equals fifteen degrees
Is the transformer charged according to the electricity bill

Power consumption = current reading last reading of meter) * current transformer ratio * voltage transformer ratio
A meter has a current of 15 degrees per degree and a 75 / 5 current transformer

How many turns of a common meter equals one degree of electricity

The dial says, for example, 720 R / kWh turns to one degree
