If one terminal of a battery is connected to the frame of the equipment in which it's used, the connection is generally made with the ground, and this is called a ground connection. It refers to the reference point from which all other electrical voltages are measured.

What is the meaning of straight and reverse polarity?

Straight polarity refers to the welding setup in which the electrode is connected to the positive terminal and the workpiece is connected to the negative terminal. Reverse polarity is the opposite setup, with the electrode connected to the negative terminal and the workpiece connected to the positive terminal. These polarity settings affect penetration, heat distribution, and weld quality in different ways.


Star-star connection of transformer?

Star Star TransformerStar Star Transformer is formed in a 3 phase transformer by connecting one terminal of each phase of individual side, together. The common terminal is indicated by suffix 1 in the figure below. If terminal with suffix 1 in both primary and secondary are used as common terminal, voltages of primary and secondary are in same phase. That is why this connection is called zero degree connection or 0o - connection.If the terminals with suffix 1 is connected together in HV side as common point and the terminals with suffix 2 in LV side are connected together as common point, the voltages in primary and secondary will be in opposite phase. Hence, Star Star Transformer connection is called 180o - Connection, of three phase transformer.Vikram Meena


Why is Earthing provided in the electrical wiring of a builiding?

The chassis of electrical equipment is typically connected to the Earth through the Ground (Earth) terminal of the electrical outlet. This is why building wiring should (or must, in many areas) include an on-site Earth ground connection. Earthing of equipment chassis is a safety measure taken to help prevent electrical shock in the event of an insulation failure or a short circuit. If there were no chassis-ground connection, a hot wire which accidentally comes in contact with the chassis could cause the user to get a serious shock. If there's no Earth connection available, use a GFCI outlet to help prevent electrocution.


If a voltmeter has one black and two red terminals how should it be connected?

The black terminal is typically connected to the negative terminal on the circuit, while one of the red terminals is connected to the positive terminal. The other red terminal is used to measure the voltage across the circuit by placing it in parallel with the component or point where you want to measure the voltage.
