Question

an electrical circuit is being discussed. technician a states that if one load is added in series, the total resistance decreases. technician b states that the voltage applied to a series circuit will be shared between each of the loads. who is correct?
select one:
a. technician a only
b. technician b only
c. both technicians a and b
d. neither technician a nor b

Explanation:

• For Technician A: In a series circuit, total resistance \( R_{total}=R_1 + R_2+\dots+R_n \). Adding a load (resistor) in series increases the total resistance, so Technician A is incorrect.
• For Technician B: In a series circuit, the applied voltage \( V_{total}=V_1 + V_2+\dots+V_n \), meaning the voltage is shared (divided) among the loads. So Technician B is correct.

Answer:

b. Technician B only
