An electric clothes dryer demands 22A from a 240V outlet at approximately 90% Power Factor. The power demand on the outlet should be about 240V x 22A x 0.9 = 4.75 kW. The active components in an electric clothes dryer are the heating element (100% PF) and the electric motor that turns the tumbler (70-80% PF).
The formula you are looking for is W = I x E. (W is watts, I is current in amps, E is volts)

Does an electric heater use less kwh on lower setting?
Yes. It draws less current.
The wiring in the wall of your house to and from an outlet has a total resistance of typically 0.12 ohms suppose a device plugged into a 120 V outlet draws 10 A of current What is the voltage drop?
Assume the supply as DC (Only resistance given) Voltage drop = 10X10X0.12 = 12V (approx)
An electric heater draws a current of 5 amps and its element has resistance of 50 ohms - if it's switched on for 5 minutes calculate the energy in kilo joule?
375 kj
You are having to reset your electric water heater breaker daily?
Likely one of the two electric elements is going out which creates very high resistance in the circuit and therefore draws very high current (amps) and causes the breaker to trip.
Does increasing the voltage to an electric heater increase the amperage it draws?
It will increase the current since the water heater is made of a heating element and which is resistive in nature. Ohms law states that V=IR where V is the voltage, I the current and R the resistance. Now the resistance will always remain constant. Thus, when the voltage is increased, the current will also increase.
How much power in watts does an electric clothes dryer use if it draws 20 amps of current from a 240 volt wall outlet?
4800 watts because watts = volts x amps.
An electric clothes dryer draws 15 A of current from a 240-V wall outlet How much power in watts does it use?
watts = volts X amps, so: 15A X 240V = 3600 watts
An electric iron always draws a current of 3.4 amp from the 220v supply line what current will this electric iron draws when connected to 110v supply line?
1.7amp
An electric clothes dryer has a resistance of 16 ohms It draws 15 A of current What is the voltage in volts of the wall outlet that it is plugged into?
We know that Voltage = Current x Resistance, so if E = I x R, then E = 20 x 12 = 240 volts, and the dryer must be plugged into a 240 volt outlet.
Does an electric heater use less kwh on lower setting?
Yes. It draws less current.
If electric heater works on 115 V and draws 3 A of current how much power does it use?
The formula you are looking for is W = I x E.
What is the resistance of a clothes iron that draws a current of 12A at 120V?
By Ohm's Law Voltage = Current x Resistance R = V / I = 120 / 12 = 10 Ohms
An electric motor draws a current of 11.5 A in a 240 V circuit What is the power of this motor in W?
11.5 x 240 = 2760W motor.
An electric clothes dryer has a resistance of 8 ohms It draws 30 A of current What is the voltage in volts of the wall outlet that it is plugged into?
Power (Watts) = Current (Amps) * VoltagePower = 22Amps * 240 VoltsPower = 5,280 Watts5280
An electric lamp is rated at 60W the current it draws from a 230 V supply is?
P=VI so I=P/V I= 60/230 I=0.261 A
A microwave oven has a resistance of 24 ohms It draws 5 A of current What is the voltage in volts of the wall outlet that it is plugged into?
Ohm's Law says Voltage = Current x Resistance V = 5 x 24 = 120 V.
The wiring in the wall of your house to and from an outlet has a total resistance of typically 0.12 ohms suppose a device plugged into a 120 V outlet draws 10 A of current What is the voltage drop?
Assume the supply as DC (Only resistance given) Voltage drop = 10X10X0.12 = 12V (approx)
