The equivalent resistance is D)
Explanation:
The equivalent resistance of n resistors in parallel is given by the equation:
For three resistors such as in this problem, the equation becomes
where we have the following:
is the resistance of the 1st resistor
is the resistance of the 2nd resistor
is the resistance of the 3rd resistor
Substituting, we find the equivalent resistance:
