I am now writing electrical power design. The first of electrical circuit.
This circuit is contain in wires, switch and lamp. I will use red colour wire for line wire and blue colour wire for natural wire.I am using line wire and this wire is supply of switch in the one slop. The another slop in wire is supply on the lamp of one slop. The nautural wire is supply in the another slop of lamp. The current is passing on line wire. This switch off time. This lamp is closed.
This switch is on time. This lamp is open.
And the another way of single phase double line with the lamp. This is two-way switch circuit. I am drawn the figure.
This figure in circuit is show that of lamp is on and off time. This circuit of application is contained (the two number of two-way switch, wires and lamp. In the figure, the line wire is supply in the switch of common point. The another switch of common point is out to the lamp of slop in supply. The first switch of last two point is supply to the another switch of two point.
In the figure, the first switch on and the another switch off. At time, this lamp is open. This lamp is lighting.
In the figure, the first switch is on and the another switch is on. At time, this lamp is closed because this current is not passing through the lamp.
In the figure, the first switch is off and the another switch is on. At time this lamp is open.
In the figure, the first switch is off and the another switch is on. At time, this lamp is closed.
