It may not carry enough voltage to power a number of functions... but what is the adapter for? The answer however is that it almost certainly will not work.

Can you use 5v 1000ma adapter on a 45v 400ma device?
No you can not. The power supply output of 5 volts is under sized. There is no way that a 45 volt device would operate from it. You will need to find a power supply of 45 volts.
What voltage will produce 3 A through a 15 ohm resistor?
V=IR so 3a x 15 ohms gives 45v
How many watts in 500 amperes welding machine?
A welding machine rated at 500 amperes uses around 120000 watts of power. This is used in very heavy industrial applications due to its large power draw.
How do you fix Bank 1 Sensor 1 signal below 45v air fuel ratio to lean?
What you have written does not sound familiar, the closest thing I can come to is that you have a low voltage reading on the upstream O2 sensor on the #1 cylinder side, replace the O2 sensor, reset the ECM and see if that remedies the problem.
How much current flows through a circuit with a 50 volt source and 30 ohm resistor?
Ohm's law is V = I·R, so:9.0 V = 0.30 A · x ohmx = 9/0.3 = 30 ohm
Did they have portable radios in the 30s?
The vast majority of radios in the 1930s were very large console radios. They had heavy wooden cabinets and looked like furniture. But they did also have portable battery operated radios too. They used a 1.5V dry cell to power the tube filaments and a 45V to 150V dry battery to power the tube plates. These batteries alone might weigh 1 to 2 pounds, so although the radios were portable they were not light weight. Also as these radios used fewer tubes than the console radios did, they usually had lower sensitivity, selectivity, and "extra features" so could not pick up as many stations or receive as many bands or produce as good sound or support "magic eye" tuning, etc.
What voltage is required to run a 75 watt light bulb if the current is 0.5 Amps?
For a resistive load like an incandescent light bulb Watts = Volts * Amps. In your home your voltage is fixed and may fluctuate somewhat due to a number of factors. The math is easy for a 60W bulb at 120 volts which yields a current of 1/2 (.5) Amps. The current for 75 W bulb at 120 V would be .625 A. You would need a 150VAC source to only draw .5 A.
Lillian mass 30.0 kg standing on slippery ice catches her leaping dog mass 15 kg moving horizontally at 4.0 ms What is the speed of Lilian and her dog after the catch?
What you want to do is first find the momentum of the dog. To find that you will just multiply mass x velocity or in your case 15kg x 4.0 m/s. Once you find that you want to equal the momentum to the momentum of Lillian. Now since Lillian is already at rest, you want to add the masses of both Lillian and the dog together since when she does begin to move, she has a combined mass of both her dog and herself. Then you want to find the missing velocity. So it should look like this: 45kg x v = 60 Now just find v and you should be good: 45kg x v = 60 45v/45 = 60/45 (divide each side by 45 to isolate v) v = 1.3333333
Is there any 0.45v dc to 220v ac inverter?
Generally, no. This ratio is an interesting one, and a random reader might infer an interest in solar cells. Irrespective of the source, .45V is so small a voltage that the inverter and/or step-up switching regulator would require huge drive and inrush currents. Doing the simple math: 220VAC requires about 600V peak-to-peak; 600 divided by about one-half volt yields a multiplication ratio of about 1200!; so, the current required at 220V (say, 2 amps) would need to be multiplied by 1200, to get about 2500 Amps RMS. Peak current for such a converter would be much higher. The basic idea is that, ignoring efficiency, volts times amps (voltage multiplied by current) should equal the same number on the input as the output. Complications ensue with peak currents and ripple voltages, but generally that product is equivalent from in to out. Write it as V * I = Watts. There are 12VDC -> 120V (US) and 12V -> 220VAC (Europe) inverters, but that's as low a starting DC voltage as I've ever heard of. Typical island home inverters using batteries expects at least 48V, to keep that ratio low. So, no.
Do you know of a replacement throttle position sensor for a Honda odyssey EX year 2000 or does the whole throttle body have to be replaced?
Just the sensor. I bought mine from eBay $60 (http://www.iapdirect.com) We need a good write on procedure though... here's what I found... There is a large misconception that Honda and Acura Throttle Position Sensors are "Riveted" in. This is false. Those "rivets" are actually screws with no head on them (They snap the head off at the factory on purpose). You can either use a flat headed screwdriver and hammer to remove them, or you can cut a slot into them with a dremmel and unscrew them with a flathead screwdriver. THE HAMMER/SCREWDRIVER METHOD:Get a good flat-headed screw driver that has a good edge on it. You need the good edge to dig into the screw material. Place the screwdriver at an angle in the position shown: Tap the end of the screw driver with a hammer. The screw will rotate counter clockwise and loosen. You should be able to finish unscrewing it with the pad of your thumb. This way is a pain. THE DREMMEL METHOD:Cut a slot into the "rivet-screw" Use a steady hand and cut carefully. Cut deep enough into the screw so that you can get a standard screwdriver blade into the slot. Unscrew the critter. RE-INSTALLING:You don't want to re-use those crappy "rivet-screws". A replacement should have screws with it. if not, go to the hardware/parts store and match the threads to a new, stainless metric bolt of the same size and length. If you have a Fast Idle Thermo Valve laying around, you can rob the screws from the cover plate, which is what I did. Make sure the Plastic tab "A" fits into the slot "B" upon re-installation. When you initially install the TPS (Throttle Position Sensor) It might be way-off.Just turn it counter-clockwise until the bolt holes line up. Screw the bolts on finger-tight, plug it in, and whip out the multi-meter! Start the car. With it Idling, Measure the voltage between the red and green wires. Adjust until the voltage reads .45V at idle. Use a multimeter to adjust it; 0.47v closed, 4.53v WOTTighten those screws/bolts down!
What size wire do you need to use to run 200 ft and have 40 amps of service?
To answer this question a voltage must be given. By using the term service I will draw a conclusion that it is a North American service of 120/240. A #6 copper conductor will limit the voltage drop to 3 percent or less when supplying 40 amps for 200 feet on a 240 volt system. If the circuit voltage is 120 volts, then a #2 copper conductor will limit the voltage drop to 3 percent or less when supplying 40 amps for 200 feet. <<<<>>>> Notice: The following calculations are wrong because a #10 copper conductor is only rated at 30 amps NOT 40 amps. To compute voltage drop (independent of voltage supply) 10 gauge wire is .9989 ohms/1000 ft to go 200 feet you need 400 ft of #10 conductor (out and back) just about 0.4 ohms I*R =E 40a*0.4Ohm =16v lost in heating the wire ( 640W ) Gauge Drop(400') #10 16v #6 6.3v #2 2.5v safety has to do with the insulation 3.4 Watts/ft will melt most plastics (#10) especially if its enclosed in conduit or worse in a wall that is insulated. bare conductors on ceramic insulators dont have a problem if this is for a resistive load the figures are correct if you are trying to run a single phase motor it may not start with #6 (starting current perhaps 7 times the running current) 45V drop if you are trying to start a 3 phase motor with #6 it may be ok only (19V drop) I do know a 7A 240V submersible well pump will not run with #10 wire (200' deep well 150' from the building) The wire coming out of the pump is #12 BTW (sales engineering) it is a GOOD idea to do some arithmetic before buying the wire.... the motor is marked with KVA class (start/run current)
What is description of bc147 transistor?
This is the European "Pro-electron" numbering system compared with the US JEDEC system (2N etc)First - LetterA = Germanium DeviceB = Silicon DeviceC = Gallium ArsenideSecond - Letter for A/B/C devicesA = small signal diodeC = small signal general purpose transistor (for audio or slow speed switching)D = power transistor (audio and low frequency applications_F = small signal RF transistorT = SCR / ThyristorU = power transistor for switching applicationsY = rectifier diodeThird + Fourth + Fifth - Unique identifier numberSome manufacturers put some significance on the number. For example Mullard/Philips treated the second digit of 4 meaning NPN Lockfit case and 5 meaning PNP lockfit. Many used 6 for TO92 cases.An optional letter followed indicating a gain grouping ... typically A being lowest, B middle and C highestDifferent manufacturers created similar transistors with different type markings.e.g. BC107 BC167 all functionally very similar.So, the BC147 is a Silicon small signal audio transistor with a "Lockfit case" originally manufactured by/for Philips/Mullard. A viable replacement today, if you can't find a 147 is a BC547 If there's a gain grouping letter, you need to match the gain grouping either by a comparable letter, or by testing. Careful with the pinout.There are a cluster of similar transistors ...So, the BC147 is one of a cluster of 3 similar transistors ... BC147/148/149. BC147 has ratings of VCE 50, VCB 45 ICMAX 100 hfe 125-500BC148 has ratings of VCE 30, VCB 20 ICMAX 100 hfe 125-500BC149 has ratings of VCE 30, VCB 20 ICMax 100 hfe 240-900 Noise 2dBLockfit transistor pinout (wideface down)BE CBC547 pinout (flatface down)E B C
