It is the thing that lights up when power is switched on.
The lamps will get dimmer. In a parallel circuit, voltage is constant. Whereas, in a series circuit, amps are constant.
2 amperes in a parallel circuit. I = W/V. It is true provided that 12v are delivered to the lamps in parallel circuit. In a series circuit, the voltage is divided among the lamps so that the total current is probably 2 amperes for all lamps.
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.
When a circuit is in off condition then it is called an open circuit..
As load is conected in circuit , so thre is no open circuit therefore there would not be any open circuit voltage.
Circuit B
It is a series circuit, where all the lamps (for instance) is on the same wire. If one lamp fails, the rest lamps will also go out.

An open circuit is called open because the circuit has an opening, a disconnection. In other words, there is an open space in the circuit in which the electrons cannot move through.

No. An open circuit is any CIRCUIT (from circle) which is not closed. That is; any break in the circle (circuit) makes it an open circuit.
Parallel circuit.
The brightness of the lights may or may not change depending on the circuit in which they are wired. In a series circuit, all the bulbs (called lamps) will experience the same current flow. The same amount of current will be flowing through each one, and each one will be dropping some amount of voltage. If we remove some of the lamps and reconnect the circuit, the lamps will glow brighter because there is less total resistance in the circuit. The remaining lamps will end up dropping more voltage, and will glow brighter. In a parallel circuit, removing bulbs (or adding them) will not affect the operation of the other lamps in the circuit (providing the voltage source is adequate). We know that each of the lights in a household circuit is wired in parallel, and turning one or more on or off won't affect the operation (the brightness) of any other light that is on.
When the lamps are in a loop, one after the other: we call this a series circuit.
