A. (pie chart) - correct answer
Galvanometer is a device used to detect an electric current.
<u>Explanation:</u>
A galvanometer is an electro mechanical instrument utilized for distinguishing and demonstrating an electric flow. A galvanometer fills in as an actuator, by creating a revolving redirection, in light of electric flow moving through a loop in a consistent attractive field.
Galvanometer is a gadget which is utilized to quantify electric flows. Note that the shunt obstruction must be low with the goal that greatest current goes through the shunt. Thus galvanometer can be utilized to gauge high flows.
Technician B is correct
It is safe to say that Lead acid uses sulfuric acid. When fully charged, the electrolyte consist of 40% concentrated sulfuric acid and the remainder consist of mostly water. However, as it discharges, both the positive and the negative plates turn into lead sulfate with the electrolyte loosing much of its dissolved sulfuric acid and water.
