The correct answer is: B. The total resistance of a parallel circuit is always less than the value of the smallest resistance.
In a parallel circuit, the current divides among the branches. This means that the current through each branch is less than the total current in the circuit. The total resistance of a parallel circuit is therefore less than the value of the smallest resistance in the circuit.
Option A is incorrect because the total resistance of a parallel circuit is not equal to the sum of the individual resistances. In fact, the total resistance of a parallel circuit is always less than the value of the smallest resistance.
Option C is incorrect because the total resistance of a parallel circuit is not equal to the total voltage. The total voltage in a parallel circuit is the same for all branches.
Option D is incorrect because the total resistance in a parallel circuit is not equal to the average
