What else can I help you with?
Would 3 neon bulbs that each use 90v at point 2mA use 90v at point 6mA if wired in parallel?
yes
What are the effects of unregulated voltage to appliances?
NORMALLY UTILITY SERVICE VOLTAGE ARE NOT STABLE AND THE WORST THAT COULD HAPPEN IS TO BURNOUT OUR SENSITIVE EQUIPMENT OR APPLIANCES DUE TO OVER AND UNDER VOLTAGE AND FREQUENT FLUCTUATIONS. IF YOU ARE USING OLD BUT SENSITIVE APPLIANCES THE BASIC SOLUTION IS TO USE AUTOMATIC VOLTAGE REGULATOR. NOWADAYS MANUFACTURERS SOLVE THIS BASIC ISSUE BY PRODUCING AUTOVOLT INPUT RANGING FROM 90V TO 260V AND CAN BE USED WITHOUT WORRIES IN EITHER 110V OR 220V SYSTEM.
Cswip 3.2 senior welding inspector exam papers?
50-90v is ocv
Can you plug your phone with 120 voltage to 220 voltage in UK?
read the label on your charger if it says 90v to 250V it will be ok it it says 120V it will not be ok
What was the voltage of early electricity?
Edison's original plan called for 90V DC (Direct Current). Alternating current is used today, due to its ability to transfer power efficiently over longer distances.
How much current flows through a circuit if the resisitance is 30 ohms and there is a 90 volt battery?
Using Ohm's Law (I = V/R), the current flowing through the circuit would be 3 amperes (90V / 30Ω = 3A).
Will a low watt transformer operate a fluorescent light bulb?
Apart from no, your question has no simple answer. Fluorescent lamps need a few kV to start them and have a 90V drop when running. All of that is provided by the "gear" needed to run a fluorescent lamp. In a compact fluorescent (CFL), the gear is inside the cap.
What power adapter do you need in the UK?
UK power supply is 230V at 50Hz. It is compatible with the rest of Europe but a continental to British connector adaptor will be required. For visitors from North America, note that the voltage is higher than US and Canadian standards. Some power supplies and equipment will operate on 90V to 260V so they will work with just a connector adaptor. That is the case for most laptop supplies. Other equipment may be fixed at 110V, in which case, they cannot be used safely in the UK without an additional power converter (a 230V to 110V transformer for example). Every power supply has the input voltage marked on it. Be sure to check each power supply before connecting it to a UK supply. Suitable connector adaptors are available in many hardware and electronics stores in England as well as in airport stores. Although the airports are the most expensive place to buy them, it saves a lot of time searching for stores that sell them. Note that the connector adaptors DO NOT change the voltage.
When one has a 240V line and checks the voltage across the individual lines why does one read 114V and the other 90V?
Where are you checking the wires at? The service panel or at the outlet? If you're checking at the outlet, it looks like some bad wiring somewhere. If you're reading this at the service panel, then the main entrance wires are faulty (or your electric company is faulty). If the outlet is unloaded you have a resistive neutral. Call an electrician now, if you value your electronics.
Will a 120v 60hz tv work on a 120v 50hz power supply?
Maybe... most modern equipment will operate on 90V - 260V so it's worth checking before buying a voltage converter for it. If the DVD player is 120V, that suggests that it is North American and will play NTSC standard discs. Using it on a 240V region means it is likely that it will be in a PAL zone. THerefore, discs bought locally may not work because of regional codings, because of the difference between PAL and NTSC and because the display may not be able to handle NTSC. Some DVD players will play any standard (NTSC or PAL) and some displays will also handle either standard. A handful of players do not have region codes either. It is worth a little more research before you assume that the DVD player will perform as you hope.
Why does AC voltage gives a electric shock and DC sources like car battery do not?
The thing that determines whether you get an electric shock is the voltage. whether the source is AC or DC is not determinant. Car batteries are usually 12v, which is not sufficient to drive a current through your skin. The voltage of Mains electricity at 110 or 220 volts on the other hand is easily high enough to give you a jolt. The fact that AC voltages are conventionally stated as RMS (a kind of average) means that the actual peak voltage will be higher still. Telephone lines carry around 90v DC when a call is incoming, which can also give you a shock. I have heard that DC is more dangerous than AC because DC tends to cause your muscles to contract, so that you grip the source, whereas AC tends to throw you off. I'm happy to say that I don't have first hand experience to confirm this!
Why current flow from higher voltage to lower voltage?
Normal flow of electrons are from positive to a less negative potential. When a potential is applied meaning voltage electrons leave their orbit and move to another nucleus leaving at the same time a hole to be fill out by the next electron coming in. In essence electrons flow one way and holes flow in the opposite direction. It is possible to have -100v flowing into a -90v. electrons do not know what the potential can be raised to all they know is the differential potential of 10 v in this caseAnswerIt doesn't. If flows from a higher potential to a lower potential. Voltage means 'potential difference', which is quite different.A 'higher potential' is conventionally taken as meaning 'more positive', while a 'lower potential' is taken as meaning 'less positive'. The direction of conventional current (plus to minus), therefore, is from a higher potential to a lower potential.Electrons, on the other hand, move from negative to positive, so they move from a 'lower potential' to a 'higher potential'.
