A. 12V, 800Ah
B. 48V , 200Ah
C. 48V, 800Ah
D. none Of above
Ans: B. 48V, 200 Ah
Explanation :
Here given that
Battery Nos = 4 batteries
Each battery Voltage = 12V
Each battery Ah = 200Ah
Battery Connected = In series
In battery series formula are given below
V=V1 + V2 + V3+ .......... + Vn
In case of series connection battery Ah remain same and battery Voltage are additive.
here battery connected in series so battery Voltage are
V= V1 + V2 + V3 + V4
V = 12 + 12 + 12 +12
V= 48 V
In series connection of Battery Ah remain same 200Ah
so here ans is 48V, 200Ah
If above battery are connected in parallel than
I=I1 + I2 + I3 + I4
I= 200 + 200 + 200 + 200
I= 800Ah
In case of parallel connection Current means Battery Ah additive and voltage remain same.
Good to Know :
If battery connected in series then battery Discharge slowly.
If battery connected in parallel then battery Discharge quickly.
If battery are connected in series and two or more bulb connected with this connection bulb dimmer because voltage not remain same for each battery.
If battery are connected in parallel and two or more bulb are connected with this connection bulb Britten because Voltage remain same for each battery.
In 110V DC voltage system , 55 Nos of 2V , 100Ah cell are connected in series so total system voltage become 110V and ampere capacity remain 100Ah, this system mostly used in 66Kv substation for protection system.
In series connection have only one current path.
In parallel connection have two or more current path.
Do not short Positive and negative terminal of battery to avoid short circuit and explosion in battery.
Do Not try to recharge non-rechargeable battery cell.
Don't try to connect battery to directly to AC supply. If we connect battery directly to AC supply Blast occurs in battery. Which cause serious injury.
Battery rated in Ah (Ampere hour).
