1 degree = kW. H, 1kW. H = J.G= 1 degree = kW. H, 1kW. H = J.G = n / kg. C = m / S

1 degree = kW. H, 1kW. H = J.G= 1 degree = kW. H, 1kW. H = J.G = n / kg. C = m / S

1 degree = 1 kW. H
1kw.h=3600000 j =3.6*10^6J
g=9.8n/kg
c=300000000m/s =3*10^8m/s

KW. H for J?

1KW*H=1000w*3600s=1000j*3600s/1s=1000j*3600=3600000j

Such as: w = Pt = uit = I square RT such a formula~
There are a lot of current, resistance, electric power, capacitance and so on. If you don't understand it, you can make it (w = Pt = uit = I square RT)
Not only Ohm's law, but also electric power, direct current, alternating current and so on. Great Xia, please look at the question and answer clearly. I don't want to solve the problem, but all the formulas for each quantity, such as: (w = Pt = uit = I square RT)

Ohm's Law: u = IR series connection: I1 = I2 = I total U1 + U2 = u total R1 + R2 = R total P1 + P2 = P total I1: I2 = 1:1u1: U2 = R1: R2 = P1: P2 parallel connection: I1 + I2 = I total U1 = U2 = u total R1 * R2 / R1 + R2 = R total P1 + P1 = P total U1: U2 = 1:1i1: I2 = P1: P2 = R2: R1 electric power: P = u ^ 2 / RP = u * IP = I ^ 2 * RP = w / T

How can t use h sometimes and s sometimes? I don't know how to use time unit when I do questions! Who can tell me how to judge which time unit to use!

When calculating kilowatt hours (degrees), the unit of time is h and the unit of power is kW
When calculating Joule, the unit of time is s and the unit of power is w, that is, 1kW. H = 1J / s * 1000 * 3600s = 3.6 * 10 ^ 6 J

The problem of physical formula w = uit
What are the units of u i t in the formula w = uit?

U uses volt, I uses ampere, t uses second

What unit is kV. A

Kilovolt ampere, a unit of power
The difference between watt and volt ampere
Watt refers to the active power, which is a part of VA
VA is usually common in the nominal power supply, as well as welding machines, transformers and other equipment with coils
Most common electrical equipment is represented by W,
In fact, VA is more accurate, which can fully reflect the power consumption of the equipment. W just represents how much work it can do, which can not fully reflect its energy consumption or supply
Actually, what I said is rather vague. You can understand it yourself, but it's very difficult,

Who can give me the basic symbol and unit of electrician? V k Ω Ω m Ω Ma Hz AC DC kW kHz MHz kV unit, be clear

5. KV voltage. 1kV = 1000V
Ω K Ω m Ω resistance. 1m Ω = 1000 K Ω = 1000000 Ω
The unit of frequency is 1MHz = 1000khz = 1000000hz
AC symbol
DC symbol
1kW = 1000 W

What is the common electrical symbol Ma Hz AC DC kW kHz MHz kV

They are: current (MA), harmonic (Hz), AC symbol, DC symbol, power (kw), harmonic (kHz), harmonic (MHz), voltage (kV)

The relationship between MV and kV in power plant enterprises
A CCPP unit is 145MW, and its output is 15.75kv
A thermal power unit is 125MW, the output is 13.8kv
Excuse me, what does this 145MW mean? It means that it generates 145000 kwh an hour?
The 15.75kv is that when he came out and received the main transformer, it was 15.75kv, and then upgraded to 220kV or 380kV through the main transformer?
Is there any connection between MW and kV? Or is there any conversion relationship?

145MW and 125MW are both power units! 145 means 145000000 joules per second of energy can be generated! Converted, that is 145000 kwh! 15.75kv and 13.8kv are the direct output voltage of generator! 1MW is equal to 1kV multiplied by 1000s! W is power unit, 1MW = 1000000wv is voltage unit

The unit given below, not the unit of power, is () a.n · M / s B.w · s c.j/s d.kw

B
N · M / S is f × v
J / S is w / T
KW is the unit of power directly
