Which is less damaging: plugging a 110-V appliance into a 220-V circuit or plugging a 220-V appliance into a 110-V circuit? …
If the appliance is an electric motor, applying too little voltage can result in overheating
. So, 220V into 110V is less damaging.
Which will do less damage plugging a 110-V hairdryer into a 220-V circuit or a 220-V hairdryer into a 110-V circuit?
which will do less damage : plugging a 110-V hairdryer into a 220-V circuit or reverse? less damage is done with a 220V Hairdryer and 110V circuit because
if it was reverse it would over heat because of too much current
.
Would you expect to find DC or AC in the filament OFA lightbulb in your home in the headlight of an automobile?
Would you expect to find dc or ac in the filament of a lightbulb in your home? In the headlight of an automobile?
Your house uses AC electricity
; your car uses DC electricity.
Why is a beam of neutrons less harmful?
The neutron was elusive because of
its lack of electric charge
. A beam of protons and a beam of neutrons of the same energy are both harmful to living tissue. The beam of neutrons, however, is less harmful. … The neutrons carry no electric charge and thus have a greater likelihood of passing through the tissue.
Which draws more current a 60 W or 100 W incandescent lamp both rated for 120 V operation?
A 60-W bulb and a 100-W bulb are connected in series in a circuit. Which draws more current? Which draws more current when connected in parallel?
60W draws more current
in a series, both are equal.
Can I use a voltage converter for my hair dryer?
You’ll need a proper voltage converter. Read our voltage guide to determine the correct size voltage converter. However, we highly recommend a
dual voltage hair dryer
for travel because the high-power travel voltage converters for hair dryers do not work very well and are only designed to work for a few minutes.
Can I use 220V hair dryer in USA?
It is also possible that a single voltage hair dryer supports a small voltage range such as 220-240V or 100-
120V
, which means that the hair dryer can handle small fluctuations in voltage. As long as the 120V used in United States falls within this range, your hair dryer will work in United States.
Why are household appliances never connected in series?
Household appliances aren’t connected in series
because if they were they would have to “share” the line voltage with the other appliances in the circuit
. Each time an appliance was added to the circuit, the voltage available to run each appliance would go down, along with the current through each appliance.
What will happen when a light bulb is removed from the circuit below?
What will happen when a light bulb is removed from the circuit below, leaving a gap? …
The brightness of the remaining light bulbs will not change
.
Why can we see the signs as Danger High Voltage rather than danger high current?
Why, then, do we see signs that read “Danger – High Voltage” rather than “Danger-High Current”. Ans. By
Ohm’s Law, current = voltage/resistance
. … The signs can only warn you of the potential of electric shock, the resistance of your body determines the current passing through it.
Does it make sense to say a textbook is about 99.9 percent empty space?
Does it make sense to say that a textbook is about 99.9 percent empty space?
Yes
. A textbook like all material things is made up of atoms, which are considered to be 99.9 percent empty space.
How do we identify an isotope?
Isotopes are identified
by their mass
, which is the total number of protons and neutrons. There are two ways that isotopes are generally written. They both use the mass of the atom where mass = (number of protons) + (number of neutrons).
Does a shell have to contain electrons in order to exist?
One electron can be boosted to many different energy levels. … (A shell is just a conceptual model; hence;
it doesn t really exist with
or without the electron,A shell is just a region of space which may or may not contain electrons,A shell is a form of energy that requires electrons in order to exist.)
Which has a greater resistance a 100 watt bulb or a 60 watt bulb?
A 60-watt bulb
has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high.
Does higher wattage draw more current?
In an absolute sense,
higher wattage does imply more power
. A lightbulb drawing 100 watts uses more power than one drawing only 50. The confusion is that power supplies are rated in watts for the maximum amount of power they can deliver.
When would you connect a 60 watt bulb to a 120 volt?
Question: Problem 3 A 60-W (60 Watts) light bulb connected to a 120-V (120 Volts) source draws a current of Answer:
0.5 A (0.5 Amps)
.
