Question

Three resistors having the same resistance value are wired in parallel. How does the equivalent resistance compare to the resistance value of a single resistor?


The equivalent resistance is thrice the value of a single resistor.

The equivalent resistance is the same as the value of a single resistor.

The equivalent resistance is one third the value of a single resistor.

The equivalent resistance is greater than the value of a single resistor.



I would think that the equivalent resistance would be half of the value of the resistor, but that isn't an option... Help me, please?

Answer 1

1/R(eq)=3/R
R(eq)=R/3

Answer 2

new i = old i * 3

new v = old v

r = v/new i = v/3i = (1/3) old r

Answer 3

I think The equivalent resistance is one third the value of a single resistor man!
