Question

The polarities of the current and voltage are indicated for each circuit element, 1-4, below. Answer the following questions with respect to the indicated polarities.

Answer 1

This question is about definitions of common electrical terms and drawing a circuit diagram with specific components.

Step-by-step explanation:

In an electric circuit, the voltage source provides the electrical energy, while the current refers to the flow of electric charge. Here are the definitions of the terms:

1. Resistor: A resistor is an electrical component that limits the flow of current in a circuit.
2. Coulomb: A coulomb is the unit of electric charge, equal to the charge of 6.242×10^18 electrons.
3. Voltmeter: A voltmeter is a device used to measure the potential difference, or voltage, across a circuit element.

To answer the second question, here is a circuit diagram that includes the given components: 2 batteries in parallel, an open switch, 2 resistors in parallel, an ammeter measuring total current, and a voltmeter measuring potential difference across one of the parallel resistors.

Answer Summary:

This question is about definitions of common electrical terms and drawing a circuit diagram with specific components.
