Answer:
Option B
Explanation:
Maintenance-free battery uses Recombination Electrolyte in order to limit the oxygen and hydrogen formation during charging.
Each plate of the battery uses a glass micro-fiber separator that absorbs the whole liquid electrolyte in its pore thus resulting in no free acid.
As the battery charges to its fullest, the oxygen produced at the positive plate moves via the pores of the separator to the negative plate.
Initially it reacts and forms , i.e., Lead Sulphate, then on further charging it gets converted to Pb, i.e., lead.
Due to this, the negative plate is not able to reach the correct potential in order to liberate hydrogen, and hence no water formation takes place.
Thus technician B is correct.
The correct option is B.
There are many hazards that may occur as a result of globalization. One of this is the violation of human right by companies. This can occur in several ways, for instance, there are some companies from developed countries which introduce hazardous technological devices to less developing countries.
Answer:
2A
Explanation:
Given parameter:
Quantity of charge = 2C
Time taken = 1s
Unknown:
The current passing through the ring = ?
Solution:
Current can also be defined as the quantity of charge that passes through a conductor per unit of time:
I =
So;
I = = 2A
