Question

Observe the given circuit and calculate the resultant resistance​

Answer 1

Answer:

10 ohm

Step-by-step explanation:

R1=4ohm , R2=12ohm , R3=7ohm

R1 and R2 are in parallel

So equivalent resistance of R1 and R2 i.e 1/R = (1/R1 + 1/R2)

= 1/4+1/12

= 1/3

R=3ohm

Now, R and R3 are in séries

So Equivalent Resistance of circuit = R+R3 = 3+7 = 10ohm

Answer 2

The two resistors offering 4ohm and 12 ohm are in parallel. Thus,1/R= 1/4+1/12 =4/12=1/3

R=3ohm

7ohm resistor is in series. Thus, total resistance= 3+7 =

10 ohm
