The brush voltage drops in dc in / of the order of 2 volts is that true?

A DC voltmeter has a sensitivity of 1000 ohm/volt. When it measures half of full scale in 100 V range, the current through the voltmeter is ??

The unit of current is: Select one: O a. volt O b. coulomb O c. ampere O d. joule

Why TR's are normal sources of DC in large aircraft instead of batteries?

Voltmeter can measure DC current a. O b. only DC voltage Oc only AC voltage both DC and AC voltage d.

14. A 6-V lead-acid battery has an A-hr rating of 180 A-hr. The battery is to be load-tested. What should be the test current, and what are the maximum permissible amount and duration of the voltage drop?

The subject is basic electrical engineering

In the figure R₁-3.41R, the ammeter resistance is zero, and the battery is ideal. What multiple of e/R gives the current in the ammeter? EH Number Units *E/R

What are the factors that affects or influence the electrical properties of a material? c) Two of you have been given two instruments with the units in ohms, your colleague measures the resistivity of the material whiles you measure the resistance. Your supervisor comes around and ask you to comment both measurements, what would you tell him?
