Advantages of Valve Regulated Lead Acid (VRLA) Batteries

Valve Regulated Lead Acid (VRLA) Batteries are sealed maintenance free lead acid batteries. The normal lead acid battery evolve  hydrogen which needs to vented through the cell in order to avoid explosion of the battery. On the other hand, the evolved hydrogen in the VRLA battery is reused in the battery itself. Therefore, no venting … Read more

VRLA Battery – Valve Regulated Lead Acid Battery

vrla sealed battery

A VRLA battery or Valve Regulated Lead Acid Battery is  a sealed battery or maintenance free battery. This is one type of Lead acid rechargeable battery. The VRLA Battery does not require stringent ventilation. Also, we can mount the battery in any orientation. The reduced ventilation requirement is an added advantage of VRLA. The VRLA … Read more

The electrical circuit comprises of so many parallel and series resistance. Both Kirchhoff current (KCL) and Kirchhoff  voltage law (KVL) is useful  for finding current and voltage in a circuit. Kirchhoff’s Current Law … Read more

What is Electric Power?Definition,Unit,Types,Formula,Solved Problems

power in dc circuit

Electrical Power Definition The rate at which work is done is called electrical power. An electrical source has  electrical charges stored in it. Therefore, the rate of transfer of electrical charges is electrical power. Thus, the more the transfer rate of the charges, the more the power of the source. In other words, the rate … Read more
