Question
The total, or equivalent, resistance for resistors in parallel is
Answer
is equal to the resistance of the smallest resistor.
is more than the individual resistance of every resistor.
is only less than the resistance of the largest resistor. It is not less than the resistance of the smallest resistor.
less than the individual resistance of every resistor.
a.is equal to the resistance of the smallest resistor.
b.is more than the individual resistance of every resistor.
c.is only less than the resistance of the largest resistor. It is not less than the resistance of the smallest resistor.
d.less than the individual resistance of every resistor.
Explanation / Answer
Here , for resistances in parallel ,
1/Rp = 1/R1 + 1/R2 + ...
considering only two resistances in parallel
1/Rp = 1/R1 + 1/R2
Rp = R1 * R2/( R1 + R2)
which is always smaller than R1 and R2
hence , similarly for any number of resistances
less than the individual resistance of every resistor.
d.less than the individual resistance of every resistor.
