Yes , a circuit without any load is a direct short.

The purpose is to eat loads and drink even more
All motor circuits require protection against single-phasing.
An unbalanced circuit refers to an electrical circuit where the components or loads are not symmetrically distributed, leading to unequal voltage or current across different branches. This can result in imbalances in performance, increased losses, and potential overheating of components. Unbalanced circuits are common in single-phase systems and can affect the overall efficiency and stability of electrical systems. Proper design and analysis are crucial to mitigate the negative effects of unbalanced conditions.
Energy sources are not always present in circuits as some circuits rely on energy harvested from the environment.
switches
The 2 simplest Electrical circuits areSeries Circuit - Same amount of current running through loads but voltage various by the resistance of the loadsParallel Circuit - Same voltage on the different loads by subject to the load resistance, the current passing through is different
There are only three parts that ALL circuits have:-- a source of electrical energy-- components that dissipate electrical energy-- good conductors to connect them together
when loads act as switches
Practically everything.
Solid State Media consists entirely of electronic components, such as integrated circuits.
The charge travels through the wires to the loads from the power source where then it powers all the loads connected on the wire. This is beneficial, but also it has its disadvantages. When one of the loads (light bulb) goes out all of the loads connected to the wire go out, instead of where in a parallel circuit the branch that has that load that went out dies. The better choice would be a parallel circuit.
Loads receive current independently of each other.

key-off loads are devices that draw current even when all switches are turned off. Examples are computer or radio memory circuits. key-off loads are sometimes referred to as parasitic drains.
