What else can I help you with?
Do potentiometers have polarity?
no there is no consideration of positive or negative legs in case of resistor.
What problems are there with reverse polarity?
Reversing polarity ,changes the rotation of the device you are changing polarity on.
What is the the instrument used too measure mass?
This instrument is an adequate type of balance.
What polarity should be used for 7018 rod?
7018 electrodes should be used with DC positive polarity. This means the electrode holder is connected to the positive terminal of the welding machine, resulting in better arc stability and smoother weld deposits.
Is a switch polarity sensitive?
Yes, a switch can be polarity sensitive, particularly in the case of certain types of switches, such as those used in DC circuits and electronic devices. For example, components like diodes or transistors within a circuit may require correct polarity for proper operation. If the polarity is reversed, it can lead to malfunction or damage. However, traditional mechanical switches, like toggle or push-button switches, generally do not have polarity sensitivity.
What electrical measuring instrument is used to measure polarity index test?
A low resistance ohmmeter is used
Does galvanometer have polarity?
No, a galvanometer does not have polarity. It is a device used to detect and measure small electric currents. The deflection of the needle in a galvanometer indicates the presence and direction of the current but not the polarity.
Do potentiometers have polarity?
no there is no consideration of positive or negative legs in case of resistor.
Which of these is the best description of a shofarA percussion instrument used by the HebrewsA wind instrument used by the HebrewsA stringed instrument used by the Hebrews?
A wind instrument used by the Hebrews
What are the two polarities used with direct current welding?
reverse polarity and straight polarity The answer is right but a bit of furthur explanation is required. Polarity can be changed in DC output welding sets. The heat of the welding arc is concentrated on the positive terminal. So when thick plates are welded as more concentration of heat is required on the job the job is kept +ve ie. straight polarity is used. For thin plates concentration of heat is on the filler rod ,so reverse polarity is used.
What is a eletroscope?
An electroscope is a scientific instrument used to detect the presence and magnitude of electric charge. It typically consists of a metal rod with a lightweight metal foil attached that can move in response to electric charges. By observing the movement of the metal foil, one can determine the presence and polarity of electric charge.
A dc voltmeter may be used directly to measure?
Polarity
Why is polarity test done?
On the CT there will be a white dot that represents a polarity mark. This is used to connect to the correct polarity terminal on the device that the CT is connected to. Additional CT transformers must be connected to the recording or monitoring device using the same polarity as the first CT.
What instrument used to study cells?
The instrument that is used to study cells is a microscope.
What are the instrument used in measuring?
Force meter is the instrument used in measuring force.
What are two examples of polarity?
-- negative polarity -- positive polarity
What instrument is used to measures mass?
This instrument is a balance.
