What is the minimum watt of a light bulb 30 40 50 60 or 70 watt for night reading?

40 watts. I did an experiment on this. Go do one and see for yourself. Sheesh. -_-


What happened to the resistance measurements if you hold the test leads tighter?

If you hold the test leads of an ohm meter together the resistance should go to zero ohms or very close. If it doesn't you're ohm meter is malfunctioning. ANSWER: Actually that is the first thing to do. It should show a zero reading If not the meter needs calibration adjustment. Otherwise the reading will be off by the that amount as true value.


How do you read a single phase electric meter?

How to Read Your Electric Meter ---- It's no mystery! Your electric meter can easily be read if you understand some basic rules. Each of the five dials represent one digit of the present reading. As you can see, the dials move both clockwise and counter clockwise. When the hand of one of the dials is between numbers, always take the smaller number. For example: 4 6 3 7 2 If you cannot tell if a hand is past a number or not, simply look at the dial to the right. If it has passed zero, then the hand is pointing to the correct number. If the dial to the right has not passed zero, then use the next smaller number. Totally confused? Let's try an example: 4 6 3 9 2 The third digit is a three because the digit to the right has not yet passed zero. If the second dial from the right was between the zero and the one, then the third digit would have been a four. Easy isn't it! To practice, go outside to your home or business and record the readings for several days in a row. By subtracting yesterday's reading from today's reading, you can get a feel for how much energy (kilowatt hours) you use each day. Keep in mind that when the power company representative reads your meter, they do NOT set it back to zero. Therefore the dials keep turning until the next time the meter is read. By subtracting two consecutive readings, the amount of kilowatt hours is determined for the month. Greeneville Light & Power System personnel use hand-held computers to record the meter reading. The computer immediately checks to see if the reading is about the same as the one the previous month. If it is quite a bit lower or higher, the meter reader is asked to re-read the dials to make sure the reading is correct. This helps insure your bill is accurate each and every month!

What does 14.65 ohms equal on the 20k setting. I got no reading on the lower settings?

The reading of 14.65 on the 20k setting means 14.65K Ohms, and you probably need to go back and re-read the instructions for the meter. If, for instance, you used a 2M scale, if you had one, you would get 0.014, but the result would not be very accurate, as you need to pick a range that is close to maximum reading for that range. It is normal procedure to start with a high range and come down in range as you approach an on scale reading.

Where can you buy a watt meter?

Assuming it for a domestic appliance, I'd for something cheap, reliable and safe like: http://www.energyoptimizersdirect.co.uk/acatalog/Energy_Devices.html Don't go buying a watt metre/meter with probes and sticking them into anything that's plugged into the mains!! Electrocution is inevitable. Good luck.
