Question 118Electricity & Electronics - Assistant Engineer

70% to pass

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

The correct answer is A) The total current flow equals the sum of the individual currents. In parallel circuits, the total current equals the sum of the individual currents flowing through each resistor. This is because the voltage is the same across all parallel branches, and the current divides up based on the resistance values in each branch. The other options are incorrect because B) the total voltage is the same across all parallel branches, not the sum, C) the total current is not the reciprocal of the individual currents, and D) the total resistance is the reciprocal of the sum of the individual conductances (the inverse of resistances), not the sum of the individual resistances.
