Q:I have cricket broadband and cannot watch vedios due to them slowing the connection, if I down load google chr?
Q:How to create an electrical connection outlet out of thin air?
Research is going on Wireless transmission of electricity in IIT, Madras, India. This will make considerable changes in how the electricity is transmitted in future certainly now, there is no way to transmit electricity wirelessly, you need to wait for some more years.
Q:Impala trunk electrical equipment?
amplifier or computer on star gps counterweight
Q:is a locomotive a safe place during a severe lightning storm or extremely unsafe?Why?
Safe. You are surrounded by metal which forms a pretty good Faraday cage. The loco is well grounded via the rails. Apart from the bang of thunder you might not even notice the lightning. The Diesel fuel is in a steel container under the loco and even better shielded than you are.
Q:none of my lights work?
Make / model and year would certainly help us help you.That must have been a big wrench to reach that far across those terminals.Hope those burns from the wrench and battery explosion are doing well. If you shorted a battery with a wrench? ( unlikely) or if you crossed booster cables, then you would have a big spark. Some burn your favourite tools . Some burn your cars computer, and a few other parts
Q:electrical outlets in a house maintain a steady voltage, even when the amount of resistance on them changes.?
Not an absolutely true statement. Even if the Voltage that feeds a house is well regulated at the input to the line that feeds the house there is still a Voltage drop across the resistance of the feeder line that varies with total house load current. Of course this Voltage drop subtracts from the no load Voltage present at the outlets. This is normally not a problem because most all home electrical equipment is designed to operate properly over the range of Voltage variations caused by normal load variations.
Q:Which type of magnet has many applications in electrical equipment?
I suppose they all do; Electromagnets are probably the most useful as they can be switched on and off instantaneously. They are used in motors, loudspeakers, relays, televisions etc. artificial permanent magnets can also be found in electric motors, loudspeakers, reed switches etc. As far as i can think natural magnets don't have many applications. but they could be used to make loudspeakers, motors and to operate reed switches for sure. So in short, they all have several applications in electrical equipment. Sorry not to be of more help.
Q:been tripped up?
shouldn't damage electronic devices unless when the GFI trips it breaks the neutral first and applies only a live wire to the device, that could damage electronic devices. It could be possible but may be rare.
Q:What are the Pros & Cons of these ratings?
Which would be the better job as far as the most interesting, important, and civilian equivalents? Gas turbine technician - electrical
Q:HOW WOULD ELECTRICAL TEST EQUIPMENT NORMally be grounded?
Ideally you want one common ground for everything. With multiple grounds, you might get voltage differences between ground points (if there are significant currents flowing) which can affect measurements. For noise isolation, some prefer to have separate grounds for power, analog and digital circuits which can be okay as long as you tie them together at a single-point ground.
