To answer this question I have to know what you are charged per Kw/hr by the power company. If you mean .10911 per kw/hr, then I need to know at what voltage.
The watt is the unit of power. For electricity, watts = volts x amps.
watts are equal to amps times volts.
No.
it draws 210 amps
Amps (current) times volts = watts. so watts divided by volts = current (Amps). i.e.- 0.5 Amps.
The watt is the unit of power. For electricity, watts = volts x amps.
Current or AMPS are what the appliance draws or load of the appliance. So, if you have a say 10,000 amps going thru a cable rated for say 1,000 amps , guess what ,the cable over heats and either will melt or at least catch fire.
The number that is on a breaker is the amount of amperage that the breaker can deliver before it trips. This is the same regardless of how many poles the breaker is.
That depends on the voltage.
On 120 v a kilowattt is 8.3 amps, on 240 v it's 4.15 amps.
watts = volts x amps kilowatt = 1000 watts
watts are equal to amps times volts.
The formula is Resistance= Voltage/ Amps(current) In your example: R=50/2.5, so the answer is 20 ohms.
Power = volts times amps, so an appliance drawing 10 amps at a line voltage of 110 volts is consuming 1,100 watts. Keep in mind, however, that in a non purely resistive load, the phase angle of amps to volts might not be zero degrees, so the calculation becomes more complex, and depends on power factor, or phase angle.
Amps can not give you a kilowatt with out a voltage being applied to the question. Watts = Amps x Volts. Amps = 1000/ Volts.
Answer for USA, Canada and countries running a 60 Hz supply service.No. Even though 240 volts uses two breakers it is still classed as a single phase service. Kirchhoff's law states that current entering a circuit is equal to current leaving the circuit. Since the appliance draws 10 amps, the whole circuit has 10 amps flowing through it.
A battery stores charge and supplies voltage and current. A kilowatt (KW) is a measure of power = Volts x Amps.
