$$\text { Figure } 6 ' 3$$ -If a fifth 10 $\mathrm { k } \Omega$ resistor is connected in series in Figure 6-3, how does V_R4 change? A) V_R4 decreases. B) V_R4 remains the same. C) V_R4 increases to 10 V. D) V_R4 increases.

Question

Quizplus · Accepted Answer

When a resistor is added in series, the total resistance in the circuit increases, which leads to a decrease in the voltage across the resistor R4S1U1B0, if the voltage source VS1 remains the same. This is because the voltage drop across R4S1U1B0 is proportional to the resistance of the resistor, according to Ohm's Law. Therefore, the correct choice is A: VS1U1B1R4S1U1B0 decreases.
