The electric circuit has a current running through it.
A short circuit is so short that all the current in the entire network prefers to pass through it! Actually, whenever in a network/circuit there are two parallel paths for the current to flow, the current chooses the path of least impedance. As such, a circuit with no impedance of any sort is called a short circuit cuz the entire current passes through it.
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
Such a circuit either has no voltage source, or some part of the circuit is open, e.g., an open switch.
Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
Circuit breakers are in place to prevent an over-current condition. When too much current is passed through a wire, it overheats and can result in fire. The circuit breaker is just doing its job when it turns off a circuit in that kind of condition. Too many appliances running simply means too much current on a circuit.
Yes, the placement of the switch does matter in a series circuit. Placing it before a component will interrupt the flow of current to the entire circuit, while placing it after a component will only interrupt the current to that specific component.
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount of current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.

In a series circuit, there is only one path for the current to flow. The current flows through each component in sequence, meaning that if one component fails or is removed, the entire circuit is interrupted.
In a series circuit, the components are connected end-to-end in a single loop, creating a single pathway for the current to flow. This means that the current passing through one component is the same that passes through all other components in the circuit. If one component fails, it can disrupt the flow of current through the entire circuit.
