What does the reading on a ammeter say when the switch is open?
An open switch in a circuit will stop all current flow so the ammeter should read zero amps.
What slows the movement of electrons?
Insulators
When capsized and floating on your back in a swift current in which direction should you point your feet?
Down current.
What should be the title of the line graph that displays data from this experiment?
Average length of fly (mm) vs. concentration of sugar (mg/mL)
How does a forehead thermometer work?
place on forehead for 4 minuites and you should get a accurate reading.
if a digital multimeter displays 000 when reading amperage, what should the technician do to get a more accurate reading?
You can always switch to milliamps for a more precise reading if necessary. Some multimeters have two As, 1 for alternating current (used for residential power and represented by the wave sign) and 1 for direct current (used in batteries and wires and represented by a horizontal line with a dotted line under it).
Is the current in the circuit 80 percent of the fuse rating?
It should be, yes. Never higher.
How would you connect an ammeter if you want to measure the current coming through some device in a circuit?
HOW TO CONNECT AN AMMETER Always connect an ammeter in SERIES in a circuit. Always ensure that the ammeter has a higher reading range than the expected current load, including start-up spikes. An ammeter expected to read a steady current of 13A should have a max range of 20A.
Should you choose current events or fantasy math for a class?
Current events I don't think your teacher would appreciate you do a fantasy math problem especially because you are not in reading class.
What is a good reading harbit?
Good reading is something that children pick up from behavior modeled by adults. Reading to children and children seeing adults read lead to higher reading outcomes. An elementary school child should read for twenty minutes a night.
What is the effect of low current in one phase of ctpt on power factor of three phase metering?
No effect. PF is determined by the load reactance, not current draw. The PT reading should remain essentially unchanged. The CT reading will reflect the lower current draw, and the metering device will simply integrate (correctly) a lower KW.
How do you change the Odo reading from Kilo to miles on a 99 expedition?
There are 2 buttons on the Trip Computer (on the interior roof of the cabin), you should cycle through the displays to the "avg mpg" or something so you can see what you're doing. Should be very simple. Good luck.
What should the mark up be on a bottle of wine in a restaurant?
it should be 30% but usually is much higher with some classy restaurants going for double the current market
Why should a statistician look at descriptive statistics along with graphical displays of a data set?
why should a executive look at descriptive statistics along with graphical displays of a data set
What does the reading on a ammeter say when the switch is open?
An open switch in a circuit will stop all current flow so the ammeter should read zero amps.
If you want to measure a current greater than the full scale deflection of the constructed ammeter in this case should the resistance in parallel with the galvanometer be increased or decreased?
A: the resistance should be decreased to 1/2 its value for half scale reading or use any ratio [ decrease] to obtain a correct reading.
When obtaining a patient's blood pressure the patient arm should be?
Resting at or just below the level of the heart. If raised higher in the air, it will affect the BP reading.
