Question

3. Three Resistance 40,50 and 200 are connected in parallel.
Their combined resistance i
​

Answer 1

Answer:

20 is answer

Step-by-step explanation:

we know formula for resistance in parallel which is

R = R1 × R2 × R3 divided by ( R1 + R2 + R3 )

by putting values in above formula

R = 40 × 50 × 200 divided by ( 40 + 50 + 200 )

R = 20 ohm
