Question

i f u connect 3 resistors, having values 2ohm, 3ohm, 5ohm in parallel, will the value of total resistance of will be 2ohm or greater than 5ohm or lie between 2ohm and 5oh? EXPLAIN

Answer 1

`(1)/(3)+(1)/(2)+(1)/(5)=\\ (10)/(30)+(15)/(30)+(6)/(30)=\\ (31)/(30)\\\\ R_t=(30)/(31) \ \Omega\approx0.97\ \Omega`

Answer 2

If u want only WHether the total resistance is less than 2 or less than 5 or more than 5 ohms: there is a Simple way.

When you connect resistances in parallel, resultant resistance is always smaller than all of them. So it is less than 2 ohms.
