# Why are amps important in electrical power units?

# What are two common units for electric power?

Watts or Kilowatts

# What are units of electrical power?

The units of power are watts, horsepower, and joules persecond.

# If you multiply electric current in amps times resistance in ohms what units will the resulting answer be in?

Voltage, measured in volts. This question is derived from the fundamental relationship between electrical components which is known as Ohms Law: V = I x R … where V = voltage (Volts), I = current (Amps) and R= resistance (Ohms).

# What is the unit of power that is equal to volts x amps?

Power=Volts x Amps Unit for power is watts

# What is the SI unit of electric power?

it is watt

# Can you use a power supply with more amps and not fry the unit?

you will need to be allot more specific on what you are trying to do here. what is the difference in amps. what is the device Generally speaking it is good practice to o…nly use the power supply that the device is rated for. the biggest issue you will have is this Power = voltage * current (simple version) if the power supply you had was 12v at 1 amps then you ca supply 12Watts of power if the power supply you had was 12v at 10 amps then you can supply 120Watts of power Just because you can supply 10 amps, and all you need is one, means your power supply is bigger than it needs to be. The device will draw what it is intended to draw. Just make sure the voltage matches.

# What is the unit for measuring electrical power?

Electrical power is measured in watts. Answer Power is measured in watts. There is no such thing as 'electrical power' as power is simply a rate. volt The basic …unit of electrical power is the watt. If the power is very large, then kilowatts (thousands of watts) or megawatts (millions of watts) are also used. Power is simply a rate, so you cannot really have 'electrical' power, 'mechanical' power, etc. In the SI system of measurements, power is measured in watts (W). Electric power is usually measured in watts, kilowatts, or sometimes megawatts. One watt is equal to one volt-ampere or one joule per second. Electric power is the rate at which an electrical circuit transfers electric energy. The SI unit of power is the watt which is one joule per second. Wattage, Watts, and (W) are what power is measured in there just different ways to say watts. "Watts" is the term used to define a quantity of power. If you were looking for a device used to measure power, that is called a wattmeter. Technically, power is a measure of how fast energy is consumed, so energy can be measured as power multiplied by time. Answer There is no such thing as 'electrical' power, as power is simply a 'rate'. Power is a measure of the rate of doing work, transferring energy, or of heat transfer. As energy, work, and heat are all measured in joules, power is measured in joules per second which, in SI, is given a special name: the watt. Another example of a 'rate' is velocity. We do not describe different times of velocity; neither should we describe different types of power. Electrical power in SI is measured in watts, or joules per second. It is equal to current times voltage, which is also equal to current squared times resistance. (P=IV and V=IR, where P is power, I is current, V is voltage, and R is resistance.) The watt is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt. The unit, defined as one joule per second, measures the rate of energy conversion.

# What is the Unit substation in electrical power distribution?

In a power distribution grid, there is a main power source from usually a generating plant or dam. It is then subdivided into 2 or more substations usually to power cities or …localities away from the power source. These substations convert the distribution voltage (several thousand volts), down to voltages that can be distributed through the locality. Further reduction of voltage occurs at individual poles that feed the business or home for 120-220 volts, etc.
