Answer:

#1/R_t = 1/R_1 + 1/R_2 + 1/R_3 + ... #.

Explanation:

They add as inverse sums, unlike in a series circuit where they are directly additive..

Answer:

The reciprocal of the equivalent resistance in a parallel circuit is equal to the sum of the reciprocals of individual resistances.

Explanation:

#1/R_p=1/R_1+1/R_2 + ... +1/R_n#
