Question

Does charge flow through a circuit or into a circuit? Does voltage flow through a circuit or is voltage established across a circuit?

A) Charge flows through; Voltage flows through
B) Charge flows into; Voltage flows through
C) Charge flows through; Voltage is established across
D) Charge flows into; Voltage is established across

Answer 1

Charge flows through an electrical circuit from the negative to the positive terminal, while voltage is established across components in the circuit, acting as the driving force for the moving charges.

Step-by-step explanation:

The correct answer to the question is C) Charge flows through; Voltage is established across. When considering electrical circuits, it is crucial to understand that charge moves through the circuit. This charge, typically in the form of electrons, flows from a point of lower potential (negative terminal) to a point of higher potential (positive terminal) in a battery or voltage source. On the other hand, voltage does not flow; rather, it is a measure of the electric potential difference between two points in a circuit. One can think of voltage as the force that pushes the charge through the circuit. Hence, voltage is said to be established across components in a circuit, like across the terminals of a battery or the ends of a resistor. An understanding of these concepts is crucial for comprehending the fundamental operations of electric circuits.
