An old topology called Token Ring
A battery will do this, when connected to a closed circuit (for a while).
To close a circuit in electrical terminology is to close any open devices that are in series with a connected load. Once this happens the current will flow through the load and the load is then termed as energised. In the case of a motor circuit the motor will operate. In the case of a lighting circuit the lamps in the circuit will energise and light the area in which they are installed.
A blowout coil connected in series with contactor's auxiliary contacts that shunt around the main contactor contacts. The coil is out of the circuit when the main contactor contacts are closed and in the circuit when the main contactor contacts are open.
If the coil is connected to a circuit and the switch is closed then, provided there is a power source, the coil will become energized.
Isolation switches can be closed with loads connected. The isolation switch should not be opened under load unless the switch is load rated. This information can be found on the isolation switch's cover as to the amount of current that can be safely interrupted.
It's called Ring.
Here are some common types of network topologies: Bus Topology: In a bus topology, all devices are connected to a single central cable (the bus). Data travels along the bus and is received by all devices on the network. Each device has a unique address, and devices communicate directly with the bus. Star Topology: In a star topology, each device is connected directly to a central hub or switch. All data passes through the central hub, which manages and controls the flow of information between devices. If one device fails, it does not affect the rest of the network. Ring Topology: In a ring topology, each device is connected to two other devices, forming a closed loop or ring. Data travels in one direction around the ring. Devices act as repeaters to strengthen the signal as it passes through each device. Mesh Topology: In a mesh topology, every device is connected to every other device in the network. This creates multiple paths for data to travel, enhancing reliability and fault tolerance. Mesh networks can be full mesh (every device connected to every other device) or partial mesh (only some devices are interconnected). Tree Topology: Tree topology combines characteristics of star and bus topologies. Devices are arranged in a hierarchical structure, with multiple star networks connected to a central bus backbone. This allows for scalability and efficient data flow. Hybrid Topology: Hybrid topology combines two or more different types of topologies to form a larger network. For example, a network might combine elements of star and mesh topologies to create a more flexible and scalable network infrastructure. Each type of network topology has its advantages and disadvantages in terms of cost, scalability, reliability, and ease of management. The choice of topology depends on factors such as the size of the network, the type of applications used, and the level of redundancy and fault tolerance required.
See related link for Network TopologiesTopology refers to the shape of a network , or the network's layout. How different nodes in a network are connected to each other and how they communicate are determined by the network's topology. Topologies are either physical or logical. Below are diagrams of the five most common network topologies.Mesh TopologyDevices are connected with many redundant interconnections between network nodes.

Ring.
Yes, a complete circuit has a closed loop for the electric current to flow. A closed circuit allows the flow of electrons from the negative terminal of the battery to the positive terminal, completing the circuit and powering the devices connected.
A network topology refers to the geometric arrangement of the actual physical organization of the computers (and other network devices) in a network. Network Topologies: Bus All devices connected to a central cable, called the bus or backbone. Bus networks are relatively inexpensive and easy to install for small networks. Star All devices are connected to a central device, called a hub. Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub. Ring All devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it. Ring topologies are relatively expensive and difficult to install, but they offer high bandwidth and span large distance. Hybrid Group of star-configured workstations are connected to a linear bus backbone cable, combining the characteristics of the bus and star topologies. Wireless Devices are connected by a receiver/transmitter to a special network interface card that transmits signals between a computer and a server, all within an acceptable transmission range.

There are really three basic types of Network topologies. They are Star, Bus, and Ring. Let me explain them to you. Star - All computers and devices are connected to a centrally located hub or switch. The hub or switch collects and distributes the flow of data within the network. It's better to use a switch than a hub because a switch transmits the data to the intended recipient rather than to all hosts on a network. Bus - All computers and devices are connected in series to a single linear cable called a trunk or sometimes called a backbone. Both ends of the trunk must be terminated to stop the signal from bouncing back up the cable. Because the bus topology does not have a central point it is difficult to troubleshoot problems. Also, a break at any point along the bus can cause the entire network to go down. Ring - In this topology, all computers and devices are connected to cable that forms a closed loop. Each computer on this type of topology acts like a repeater and boosts the signal before sending it to the next computer. It transmits data by passing a "token" around the network. Hence this type of network is commonly called a token ring network. Similar to the Bus topology, if one computer fails, the entire network goes down.

When switches or any circuit opening devices are in series with each other, they all have to be in the closed position to energize the load.When switches or any circuit opening devices are in parallel with each other, any one of the switches or circuit opening devices in the closed position will energize the load.
Any closed bounded subset of a metric space is compact.
There are more than a way to define the closed set:A set is closed if and only if its complement is opened.A set is closed if it contains every limit or accumulation points, the points contained in the set S instead of themselves.
