Chapter 10, Problem 9RQ

Does electric charge flow across a circuit or through a circuit? Does voltage flow across a circuit or is it impressed across a circuit? Explain.

To determine

To detremine: Whether the charge flow and voltage flow takes place across a circuit or through a circuit.

Answer to Problem 9RQ

The charge flow takes place through the circuit and voltage flow takes place across the circuit.

Explanation of Solution

The charge flow is same as the movement of the charge per unit time between different positions in the metal. The charge flow takes place between various positions due to external factors at different positions. The external factor is called potential. The difference in the potential between different positions is called potential difference or voltage.

The charge flow takes place through the circuit because the charge passes from every position between different positions. The voltage is applied at the ends of the different positions, so the voltage flow takes place across the circuit.

Conclusion:

Therefore, the charge flow takes place through the circuit and voltage flow takes place across the circuit.
