Chapter 35, Problem 32A

Hector says that adding bulbs in series to a circuit provides more obstacles to the flow of charge, reducing current in the circuit. Jeremy says that adding bulbs in parallel provides more paths so more current can flow. With whom do you agree or disagree?

To determine

Whether you agree with Person J or Person H.

Explanation of Solution

Introduction:

The current always tries to flow through a minimum resistance path. If the resistance in a path increases, the voltage to flow of electrons decreases due to loss of power in the form of heat.

In a series circuit, the total resistance increases due to the addition of more bulbs. The resistance of each additional bulb increases the resistance for the flow of current. So, the current in the circuit decreases due to more obstacles for the flow of charge.

The charge always tries to flow through the path of minimum obstacles. In a parallel connection, the addition of more bulbs provides more paths to flow the charge. The total current by the addition of bulbs increases due to an increase in the bulbs for the flow of charge.

Conclusion:

The statement made by Person J about the flow of current is correct.
