Which of the following statements is true concerning circuits with parallel connected resistances?

AThe total current flow equals the sum of the individual currents.
BThe total resistance equals the sum of the individual resistance.
CThe total current flow equals the reciprocal of the sum of the individual currents.
DThe total voltage equals the sum of the individual voltages across each resistance.
AI Explanation

The correct answer is A) The total current flow equals the sum of the individual currents. In a parallel circuit, the total current flow is equal to the sum of the individual currents flowing through each parallel branch. This is because the voltage is the same across all parallel branches, and the current divides based on the resistance of each branch. The total resistance in a parallel circuit is less than the resistance of any individual branch, which allows more current to flow through the circuit. The other options are incorrect because B) the total resistance is the reciprocal of the sum of the individual resistances, C) the total current is not the reciprocal of the sum of the individual currents, and D) the total voltage is the same across all parallel branches, not the sum of the individual voltages.
