Question

Two of the three resistors in the figure (Figure 1) are unknown but equal.Is the total resistance between points a and b less than, greater than, or equal to 200??

The total resistance between points a and b is less than 200? . The total resistance between points a and b is greater than 200? . The total resistance between points a and b is equal to 200? . Two of the three resistors in the figure (Figure 1) are unknown but equal.Is the total resistance between points a and b less than, greater than, or equal to 200?? The total resistance between points a and b is less than 200? . The total resistance between points a and b is greater than 200? . The total resistance between points a and b is equal to 200? .

Explanation / Answer

Since the resistances are in parallel,

(1/total resistance) = (1/R)+(1/R)+(1/200)

Whatever positive value R takes, this sum will be higher than 1/200

Therefore, the effective resistance between a and b must be less than 200 ohm
