Question

Calculate the equivalent resistance of three resistances 3 ,4 and 6
when they are connected parallel​

Answer 1

Answer:

The equivalent resistance is 1.33 ohm.

1/3 + 1/4 + 1/6 = 9/12

= 3/4

= 1.33 ohm

Answer 2

Explanation:

for parallel connection reciprocal of equivalent resistance = 1/r1 + 1/r2 + 1/r3

• = 1/3+1/4+1/6
• = (1×4 + 1×3 + 1×2 )/12
• = (4+3+2)/12
• = 9/12
• = 3/4

so, equivalent resistance = 4/3
