Outside and in wet areas are two examples, there may also be other circumstances where there is a risk of electrocution when a RCD should be used. When in doubt use one, they don't cost much and any hardware store has them. Be aware though they are not fool proof. (since fools are such ingenious people)

What is residual voltage for DC generator?
This case arises only in series dc generator current should be sent around the poles to magnetize. this current can the source(generator). current is passed through poles if it is loaded. but if it is not loaded current is zero through the field. load voltage should be zero actually.but this dont happen.we use generator frequently.due to this poles are partially magnetized this causes some voltage appear called residual voltageAnswerThere's no such thing as 'residual voltage'; you're confusing it with 'residual magnetism', which exists in the magnetic poles of a self-excited d.c. generator and which enables the build-up of its terminal voltage.
What is rated normal current?
The rated current is the maximum current that can be drawn in normal continuous use, without any reduction in the lifetime of the device.
What should the current be through a bleeder resister in a voltage divider circuit?
The current should be high enough to maintain the voltage at each division. Generally, the current should be ten times the load current or the voltage will be across the voltage divider. If possible use regulators or zeners or regular diodes. I'm not saying dividers are bad but there are less current sensitive solutions.
What part of a circuit dissipates energy?
A: ANY part that uses current to do the work will use some of the input energy to make it operational. this energy is called dissipation of the device and it is wasted as heat
How do you do earth testing?
One way of "Earth fault testing" is to use a High Pot device. This send a high voltage with a very low current through the equipment and will tell you when there is a leak to ground.

Can you use a 1000mA current when the device requires a 450mA?
Current is determined by the load. If your load device requires 450 mA, then it will draw that amount of current from the supply.
How should a person treat a mattress that might have fleas on it from infested puppies?
I would use a non residual aerosol labeled for fleas with a growth regulator. You should use non-residual only on a mattress to avoid irritation.
Can i use pir device on extraction fan?
If the device is the correct voltage, can handle the current (and I mean surge starting current, not running current. Significant difference), and doesn't mind an inductive load (Get one for a light with a transformer in it (Soduim arc, mercury arc)) it should be fine.
Which device you use to convert the direct current into AC?
Invertor
Can you use adapter with output 5v 3amp to operate adevice with 5v 1amp?
Absolutely. The first rule: Source voltage should be equal to the device voltage. The second rule: Source current sould be higher than the cumulative of the device's current.
What is the difference between 50N and 50G RELAYS?
50N: Instantaneous Earth Fault Relay50G: Instantaneous Ground Fault Relay50N is main EF protection device but 50G is standby as backup of main device.50N use for motor starters but 50G use for feeders.50N see zero sequence of EF current but 50N see residual current due to sum of three CT.If you have a resistance grounded system, a 50N may not see enough ground current to trip properly. If you do not have a resistance grounded system, a 50G may create nuisance tripping.
What is rated normal current?
The rated current is the maximum current that can be drawn in normal continuous use, without any reduction in the lifetime of the device.
How do I use gps tracking equipment for a trip?
Once the device is turned on the GPS should be able to track where you currently are. When that is established go into the devices main menu and find where you can enter in a current and desired location. Once entered the device should give you a route to get to your destination.
Which type of sharpening device should I use with my cutlery Manual or electric?
You should use a manual sharpening device because electrics can wear a knife down.
Which device should you use to connect subnetworks?
Router
Why potentiometer is more accurate than voltmeter?
volt meter draws current from the device whose reading is to be taken and potentiometer does not draw current from the device so it is better to use potentiometer than voltmeter
