Question

Calculate the electric current in the given circuit when both keys are closed.

The easiest-to-understand answer will be marked as brainliest! :) Thanks in advance x

Answer 1

Answer:the correct answer is 4v

Answer 2

Answer:

Resistance of BC & AD (parallel combination)

1/4 + 1/4

2/4

1/2

2ohm

Now , we'll take resistance of BC & AD IN SERIES AS 2 OHM.

Similarly , Resistance of AC & BD (parallel combination)

1/4 + 1/4

2/4

1/2

2ohm

Now , we'll take resistance of AC&BD IN SERIES AS 2 OHM.

Total resistance of circut(in series) = resistance of AC&BD + resistance of BC&AD

2+2

4ohms.

current drawn = V/R ( FROM OHM'S LAW)

12/4

3A.

• Note that resistance in series (R) = sum of total resistances i.e R1+R2+R3.......SO ON &
• Resitance in parallel 1/(R) = 1/R1 + 1/R2 .....so on
