Electricity and Circuits Investigation in Team LL

25/11/2020

Team LL have been thoroughly enjoying their science work linked to electricity and circuits. This week they have been generating possible investigation questions and creating vocabulary checklists. In pairs the children have chosen their own investigation question. They carried out their investigation and wrote up their findings.

A typical residential home uses alternating current (AC) electricity. AC is normally delivered via electricity transmission lines, which run along roads and highways, and is transmitted to local substations. These substations convert the electricity into direct current (DC), the type used to power household devices. The electricity produced at substations ranges from 120 VAC/240 VAC to 277VAC/500 VAC depending on the locale.

Electricity is created by connecting a generator to a motor and sending it through a series of gears. The gears create a constant motion, which in turn creates a continuous flow of electrons -- the electricity. The electricity travels from the generator to the motor through wires called conductors. The number of conductors inside a wire varies based on the size of the current being delivered. Smaller amounts require fewer conductors than larger amounts.

The speed at which the generator turns determines the frequency at which the electrons oscillate. Higher frequencies mean lower voltages. Lower voltages mean higher voltages. Voltage is measured in units of Volts. Most commonly, 110 VAC is used in North America, 115 VAC is used in Europe and 240 VAC is used in Australia. Frequency is measured in hertz and ranges from 50Hz to 60Hz.

A three phase system consists of three separate circuits, each with a different frequency. Each circuit is separated by two magnetic poles of opposite polarity (like north and south). Three-phase systems have been used since the 18th century to generate electricity because they allow for much greater efficiency.

Three-phase power is often preferred by companies for its stability and reliability. However, most small scale applications do not require this level of control due to the relatively large cost involved in installing the equipment. Instead, a single line can serve many smaller loads without any problems.

One disadvantage of three-phase power is that it produces less torque than single-line power. Another disadvantage is that if one phase fails, it affects other phases. Additionally, three-phase power is more expensive to install and maintain.
