Q2/Choice the correct answer 1. The energy storage capacity of a cell is determined by the: (a)terminal voltage (b) Electrolyte specific gravity (c) Amount of material available for chemical reaction (d) None. 2. The reason for having an even number of positive plates in a lead-acid Battery is because: (a) primary and a secondary cell (b) positive plates distort when chemical reactions take place on both sides (c) positive plates distort when chemical reactions take place on one side (d) Negative plates distort when chemical reactions take place on both sides. 3. The only accurate and practical way to determine the condition of the lead- acid battery is with a: (a) Specific gravity check of the electrolyte (b) Measured discharge in the workshop (c)Check of the terminal voltage (d) Check the terminal wire. 4. An out of balance condition in an AC three phase system can be detected by means of: (a) Voltage sensors connected across each outputline (b) a current transformers connected in the neutral line (c)a dedicated field coil monitoring circuit (d) a current transformers connected in the output line.

Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
