There is an ammeter and a bulb on the main road, and two bulbs on the branch road. Which bulb does the ammeter measure

In the trunk circuit, the ammeter measures the total current, which belongs to the hybrid circuit. Two bulbs on the branch circuit are connected in parallel, and the two bulbs are connected in series with the bulbs on the trunk circuit. Therefore, the ammeter and the bulbs are connected in series to measure the total current

There are 1600 cycles per kilowatt hour on the household electric energy meter. When using the bulb, the meter turns 32 times in one minute. How many kilowatt hours does the bulb consume in one minute?
Seeking process

1600r / kW · h is 1kW · h for 1600 turns
So 32 turns is 32 / 1600 = 1 / 50KW · H = 0.02kw · H
The bulb consumes 0.02 kwh in 1 minute
1 minute = 1 / 60 hours = 1 / 60 hours
Then the power of electric lamp P = w / T = (1 / 50) / (1 / 60) = 1.2kW = 1200W

The meter lights flash very fast, and the meter goes very fast
I've just rented a house. It doesn't seem to matter if I turn on the light. The meter has only gone for a long time, But I bought a hot water block a few days ago to boil water. After I plugged it in, the indicator light of the meter kept flashing once in a second or two, and the meter went fast. In a few minutes, it went 3-4 grid. I see that the above is kW. H, which means that I used 3-4 kilowatt hours after I burned water for a few minutes. That's terrible. What's the reason? The landlord moved his hands? But it's too exaggerated
At first, it was 002222, but now it's 002236
How to do? It hurts to use hot water

You don't have to worry about this. I believe the landlord doesn't have such good skills. 2. Reading electricity meter requires arithmetic. Kwh means kilowatt hour, that is, if one kilowatt doesn't calculate active power and reactive power, it is one hour per kilowatt. But the number of meter turns is not the number of degree, there is a turn on the meter
