Question

Why two batteries are connected in parallel

Answer 1

Answer:

So that the output is doubled and the electricity provided is of higher voltage.

Explanation:

When you connect two identical batteries in parallel, you double the output capacity while keep the output voltage the same as either battery. In the other case, if two identical batteries are connected in series, the output voltage is doubled but the output capacity is kept the same as either battery.

Answer 2

Dear

We connect them to minimise the energy loss and to get a secure connection

Even if the circuit is broken then other appliances wont stop working!

Hope you understood!
