When a vcr is connected across a 120 v outlet the vcr has a 9.5 a current in it what is the power rating of the vcr?

Power = Voltage * Current, so 120V x 9.5A = 1140 Watts. What the hell VCR draws 1140 Watts, though? Even early Sony U-Matic VCR's with mechanical everythings drew only 100 Watts.

What is a fuse rating?
Fuses have two basic ratings. The first is current rating. The current rating is the amount of current that a fuse will safely pass before blowing. When the current flow through a fuse exceeds its rating, it opens up and breaks the circuit. If a fuse has a 5 A rating, it will open as current flow through it exceeds 5 amps. It is useful to note that there are some fuses that are designated as time delay. These fuses will sustain current in excess to their current rating for a short period before blowing. The fuse that blows immediately when its rated current is exceeded is an instantaneous fuse. The other way fuses are rated is by voltage. So when selecting a fuse, be sure that both the current and voltage rating are suitable for the application.Fuse rating is the permissible minimal current to pass in the fuse element,without causing the fuse to blow or melt.

WHAT IS rectifiers 1N4007?
The 1N4007 is a diode with forward current rating of 1 ampere, and a reverse voltage rating of 1,000 volts.
What if two current source connected in series?
Theoretically not allowed and practically not safe or desirable to have two current sources in series or two voltage sources in parallel. In practice, the sources will get hot and catch on fire -- very unwise to even try.
Will the current in the light bulb connected to a 220v source be greater or less than when the same bulb is connected to a 110v source?
A: The current is not a function of voltage available but rather the power needed to light the lamp. To answer your question a 100 watts lamp will require 1.83 times more current for a lamp rated as 100 watts at 120 volts.It is a basic ratio 220:120AnswerI disagree with the previous answer. The power rating of a lamp only applies when the lamp is subject to its rated voltage -which is why both values are shown on the lamp (e.g. 60 W / 120 V).So, if you subject a lamp to less than its rated voltage, it will not achieve its rated power. In fact, the decrease in power will be significantly greater than the corresponding decease in voltage. It will certainly not 'compensate' by drawing more current!However, to directly answer your question, the current drawn by a lamp connected to a 220-V supply will indeed be greater than the current drawn by the same lamp connected to a 110-V supply.
What is the power rating of a lighting bulb when 0.8 a flow through it when connected to a 120-v outlet?
96watts
Do the outlet devices must have an ampere rating not less than the load to be served?
The receptacle must have a rating equal to or greater than the connected load.
When capacitors ate connected in series the capacitance increase or decrease?
Capacitors in connected in series result in a higher voltage rating, but lower capacitance. Two 470uF 50V capacitors connected in series will give you a total of 235uF, but you can put up to 100V across the series combination. Two 470uF 50V capacitors connected in parallel will give you a total of 940uF, across which you can put 50V (the voltage rating does not change for capacitors in parallel).
Why SCRs are connected in parallel?
When the load current exceeds the SCR current rating, SCRs are connected in parallel to share the load current. Further the holding currents of the devices should not be so much different that at reduced load current one of the device gets turned-off because of fall of current through it blow its holding current value.
What is the current through the 150 ohm resistor?
It depends on the voltage applied across it. But the maximum current is limited by the power-rating of the resistor (power divided by the square of the voltage).
Can you plug a 115 volt 15 amp airconditioning unit to a 100 volt outlet?
I have never seen a 100 Volt rated outlet. Usually outlets would be rated for 110 to 120 volts for residential use, or maybe 150 volts. The rating is separate from what voltage the outlet is providing. If your outlet is supplying 100 volts, as measured by an accurate voltmeter, you have some problem in your wiring or a faulty outlet. If there is only 100 volts at the outlet get an electrician to diagnose the problem if you are not completely familiar with home wiring. In general you should never use an outlet that has a voltage or current rating less that the device will consume.
Can you use a French socket in Denmark?
There are two facets to this question: Can it be used safely, and can it be used legally. This applies to foreign fixtures in any country. This is a matter of the rating on the components. You cannot exceede the voltage capacity of the outlet or it will arc internally. The voltage of the circuit feeding the outlet must be the same as the voltage the outlet is designed for. You can use a 220V US NEMA outlet on European 220V safely, but you can't use a US 110V outlet. Also, the overcurrent device on the circuit must be less than or equal to the maximum current rating on the fixture. A 10A or 15A breaker is okay for a 110V 15A US outlet, a 20A breaker is not. If you respect the voltage rating and insure the current rating will not be exceeded, the fixture should be safe. This is another matter entirely. It is a matter of wether or not whatever regulating body that certified the outlet is recognized in your country. You will need to contact your local building inspector / code inforcement person to find out for sure. I wouldn't get my hopes up.
How many receptacle can you put on a run?
In Canada there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.
Why is there a limit to the number of devices that may be connected to a single electrical outlet?
The cabling to the outlet can only handle a maximum power. For safety reasons, this is limited to far below the fail level by a fuse or circuit breaker. If you exceed the power rating, you run the risk of causing a fire.
How do you calculate mcb rating?
Circuit breakers are used to protect the conductor that is connected to it. The sizing of the conductor is based on the current of the load. As the connected load current is increased so must the wire size to accommodate that higher current. Therefore as the wire size increases so must the breaker size to accommodate the higher load current.
What must be the same for any two resistors that are connected in series?
The current in each.
What kind of outlet is needed for a sump pump?
Outlet rating should be suitable to the rating of the motor. The type should be preferably IP 55 or higher if mounted outside the sump in dry area.
