What is the current in the hair dryer if it is plugged into a 110- V outlet?
Without knowing the wattage that the hair dryer is rated at an amperage can not be stated. If you find the wattage, use this equation to find the amperage. I = W/E, Amps = Watts/Volts.
Do you need a 110 v power strip to plug into 110 v outlet?
Nominally 110 to 120 volt power strip is okay to connect to a standard outlet.
If you plug a toaster rated at 110-v into a 220-v outlet current in the toaster will be?
hi woo
Why do some machine needs 220V 0V rather using 110V 110V with ground?
If a machine uses a motor or resistance load greater than the typical capacity of a 15 Amp 110 V outlet, the device will be designed to use 220/240 V. The same wattage, at 240 V, will be available with lower amperage and can be supplied with smaller wire using a 240 V circuit. Example: 2600 Watts at 240 Volts = about 10.8 amps However, the same wattage at 120 Volts = about 21.6 amps, larger than a typical residential outlet could handle.
How much current flows through a toaster with a resistance of 20 ohms when it is connected to a 110 volt outlet?
Ohm's Law Volts = Current x Resistance Amps = V / R 110 / 20 = 5.5 Amps
What will consume more wattage - a 110 volt appliance drawing 10 amps or a 220 volt appliance drawing 8 amps?
The equation for wattage is W = A x V. Substitute your values into this equation and you will have your answer.
How do I calculate wattage?
Wattage, you mean power. Power = V * I. V - the voltage and I the current.
How do you change a 110 socket outlet into a 210 socket outlet?
You probably mean to change it to a 240 V outlet... either case, you'll need to run a new wire and install a new breaker.
I have a 150 - 250 V input cord on a step up and down transformer for 110 or 220 voltage output. Is it safe to plug this into a 110 V wall outlet considering the rating at 150 V?
That cord is all right for all voltages up to 250 v including 110 v, but the current drawn in amps must not exceed the rating of the cord, or it would overheat.
Can you plug a 100-240volts power adaptor to a 110-220volts outlet?
Yes, the adaptor can take anything from 100 to 240 v.
Wattage needed for 750 milliampre?
That depends on the voltage V. Wattage P = amperage A times voltage V.
How you determine wattage?
wattage is nothing but power product of current and voltage p=v*i
