* **In a series circuit, the current __ B) is the same at all points.** This is a fundamental principle of series circuits. The current has only one path to follow.<br /><br />* **Adding loads in a series circuit is similar to __ D) increasing the length of a wire.** Just like a longer wire offers more resistance to current flow, adding more loads (resistors) in series increases the total resistance of the circuit.<br /><br />* **As more bulbs are added to a series circuit, each bulb will __ D) less intensity.** With more bulbs (resistors) in series, the total resistance increases, and since the voltage source is constant, the current flowing through the entire circuit decreases. This reduced current results in dimmer bulbs.<br /><br />* **In a parallel circuit, IT (total current) is equal to __ the sum of the individual branch currents.** This is expressed as I_T = I₁ + I₂ + I₃... In a parallel circuit, the current splits into different paths, and the total current is the sum of the currents in each branch.<br />
