What is the meaning of the word calibrated?
The word "calibrated" refers to the process of adjusting, measuring, or standardizing a device or instrument to ensure accurate and precise results. It involves setting or aligning the instrument to a known reference or standard to ensure its measurements or readings are reliable.
Can an ohmeter measure the value of a resistor when it's already in the circuit?
It can be difficult to directly measure a resistance while it is in circuit. Generally, other parts of the circuit will have an effect on the readings an lead to errors that are difficult to predict. If the other parts of the circuit are understood, it may be possible to calculate the total theoretical resistance from the component values and then compare it to an actual reading. This is often unreliable because it doesn't prove that a specific resistor is a certain value. It is almost always better to power the circuit and use a voltmeter to establish the voltages at different points in the circuit. If the circuit is understood, voltage readings can often show faults in resistors or other components very quickly. Alternatively, voltage readings can be used to ascertain a resistance value if it isn't marked. Whatever the task, there is always an amount of detective work and the route to take depends very much on the circuit, hence there are no specific examples mentioned here.
When you are at rest and supported byva pair of weighing scales how does the sum of the scale readings compare with your weigh?
The sum of the scale readings will always equal your total weight.
Which instrument do you use to compare the length of segments?
ruler
How do you check calculation of current temperature on a min max thermometer?
Compare the readings at the end of the red line.
What can you compare a human eye to an optical instrument?
A camera or a telescope (:
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?
u see the light bulbs on a series circuit's brightness evolves and the brightness on a parallel's circuit dont
How do you test the coil pack?
If you have an Ohm meter you will want to measure the resistance (ohms) of the Primary and Secondary sides of the coil pack and compare your readings to the Specifications for the vehicle.
Nellie newton hangs at rest from the ends of the rope as shown how does the readings on the scale compare with her weight?
If only I knew as well, then my homwork would be easier too. :P
Is there an online Guitar Store where I can compare features of different electric guitars?
Www.musiciansfriend.com is probably the most comprehensive musical instrument store online. You can compare features of various electric guitars there.
How do you test a Pressure differential switch in a high efficiency furnace?
A manometer with two ports (digital or magnahelic), is best. Compare readings to published values or what is stamped on switch. One will be positive and one will be negative. If only single port gauge used, add positive and negative readings together, to get total.
Compare the phase relationship between the voltage and current in a purely resistive circuit and an RL circuit?
In a pure resistive circuit the voltage and current are in phase. In an inductive circuit they are fro zero to 180 degrees out of phase. If they are in phase the Power Factor is 1 and 180 degrees the PF is zero. The exact amount of the phase difference depends on the specific circuit.
