In summary, the conversation discusses a circuit with two 1kΩ resistors in parallel and the question of why the 1kΩ resistor with the voltage source has higher current. The conversation also mentions the use of an android app called 'EveryCircuit' for simulating circuits and suggests redrawing the circuit to better understand it. The conversation briefly mentions Kirchhoff's laws for electric circuits.

I have tried my best but can not figure out how this circuit works. Is the 2 1Ks in parallel? Why does the 1k with the voltage source have higher current?[/B]

That's a neatly drawn schematic. Did you draw it or is that how it was given to you?

All circuits work on the basis that battery current leaves the + terminal and makes its way back to the battery's – end via external elements.

In your circuit, the current has to pass through the first 1kΩ resistor, but then it can split when it finds there are two separate and independent paths it can take to get back to the battery's – terminal.

strictly speaking, we could say there are 3 separate paths because the voltmeter itself presents an additional high-resistance path

It's an android app called 'EveryCircuit'. It is very useful for simulating a wide variety of electrical and electronic circuits.

Yes. Have you studied the Kirchhoff's laws for electric circuits?

Perhaps redraw the circuit with the voltage source moved to the left hand side and with higher voltage nodes at the top and lower voltages at the bottom of the drawing. It should help your understanding of the circuit.

What is a simple circuit?

A simple circuit is a basic electrical circuit that consists of a power source (such as a battery), a conductor (such as a wire), and a load (such as a light bulb). It allows electric current to flow from the power source to the load, producing light, heat, or some other form of energy.

What are the components of a simple circuit?

The main components of a simple circuit include a power source, a conductor, and a load. Other components may also be included, such as switches, resistors, capacitors, and diodes, depending on the specific circuit design and function.

How does a simple circuit work?

A simple circuit works by allowing electric current to flow from the power source through the conductor, which then powers the load. This process happens continuously as long as the circuit is closed and functioning properly.

What is the difference between an open and closed circuit?

An open circuit is one in which the path for electric current to flow is broken, preventing any current from flowing. A closed circuit, on the other hand, is one in which the path for electric current to flow is complete, allowing current to flow freely through the circuit.

How can I make a simple circuit at home?

Making a simple circuit at home can be done using a battery, a light bulb, and some wires. Connect one end of a wire to the positive terminal of the battery, and the other end to one end of the light bulb. Then, connect another wire from the other end of the light bulb to the negative terminal of the battery. This will create a closed circuit and the light bulb should light up!
