Question

Find resultant resistance when 4ohms 6ohms are connected in parallel​

Answer 1

Answer:

Explanation:

formula for effective resistance in parallel- 1/r1 + 1/r2

so resistance here = 1/40 + 1/60 ohm

= 3/120 + 2/120 = 5/120

= 1/24

= 24 ohm ( we reciprocate the no. obtained to get the actual resitance)

hence the resistance obtained is 24 ohm

Answer 2

Answer:

2.4 ohms

Explanation:

When 4 ohms and 6 ohms resistors are connected in parallel, the resultant resistance will be :

     R1 * R2 / R1 + R2

=> 4 * 6 / 4 + 6

=>  24 / 10

= 2.4 ohms
