# Explaining DC Open vs Closed Circuits Simplified

• eric0524
In summary, the difference between a DC open circuit and a closed circuit can be explained by thinking about the flow of current. An open circuit has a broken loop, while a closed circuit has a complete loop, allowing for current to flow. This can be visualized using the water theory, where an open circuit is like a leak in a pipe, while a closed circuit is like a continuous loop.

I am trying to find a extremely simple answer to explain the difference between a DC open circuit and a closed circuit. I tried to explain it with the water theory but that didn't work so well.

Thank you for the reply this thread is now complete. (not sure why none of the posts showed up but it's solved)

Basically think about if there's a full circuit "loop" for current to flow. An open circuit has an open or broken loop. An closed circuit has a closed or complete loop.

Left is open. Right is closed.

## 1. What is the difference between an open and closed circuit?

An open circuit is a circuit where the current cannot flow through due to a break in the circuit, while a closed circuit is a complete loop where the current can flow through.

## 2. How does a DC open circuit work?

In a DC open circuit, the current is unable to flow due to a break in the circuit, typically caused by an open switch or a disconnected wire. This prevents the flow of electrons and results in no power or energy being transferred within the circuit.

## 3. What is the advantage of a closed circuit in DC?

The advantage of a closed circuit in DC is that it allows for the flow of current, which is necessary for devices to function. In a closed circuit, the current can flow from the positive terminal of the power source, through the circuit, and back to the negative terminal.

## 4. How does a DC closed circuit work?

In a DC closed circuit, the current is able to flow continuously in a loop, providing power to the devices connected to the circuit. The current flows from the positive terminal of the power source, through the circuit, and back to the negative terminal.

## 5. What happens if there is a break in a DC closed circuit?

If there is a break in a DC closed circuit, the current will stop flowing and the devices connected to the circuit will not receive power. This can be caused by an open switch, a disconnected wire, or a component failure. It is important to ensure that a closed circuit remains intact for proper functioning of electronic devices.
