attract the attention of potential customers‚ or as part of a decoration. For this holiday homework‚ you should complete the following requirements: 1. LED Sign： Everyone should make an LED sign. A simple one containing a single series circuit is OK. You need to determine the materials to make the sign from and prepare them by yourselves. You can design your own symbol used in different ways. 2. A report： Make a report to introduce the LED sign you make. The planning and report

McClain Baxley A circuit is a closed loop that electrons can travel in. A source of electricity‚ such as a battery‚ provides electrical energy in the circuit. Unless the circuit is complete‚ that is‚ making a full circle back to the electrical source‚ no electrons will move. There are three essential parts to a true circuit. These include electrical devices. An electrical device is a device that resists the flow of energy. Another electrical device that a successful circuit must have is a source

test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the tester. The tester consists of an indicator in series with a source of electrical power - normally a battery‚ terminating in two test leads. If a complete circuit is established between the test-leads‚ the indicator is activated (the indicator may be an electric light or a buzzer)

A clamper is an electronic circuit that fixes either the positive or the negative peak excursions of a signal to a defined value by shifting its DC value. The clamper does not restrict the peak-to-peak excursion of the signal‚ it moves the whole signal up or down so as to place the peaks at the reference level. A diode clamp (a simple‚ common type) consists of a diode‚ which conducts electric current in only one direction and prevents the signal exceeding the reference value; and a capacitor which

that any resistive circuit or network‚ no matter how complex‚ can be represented as a voltage source in series with a source resistance. It is used to simplify the load analysis of series-parallel circuits. 2. What is VTH ? How is it measured? Thevenin voltage. In a series-parallel circuit is the voltage present at the output terminals of the circuit when the load is removed. Even though it has a new name VTH is nothing more than the no-load output voltage VNL for the circuit. Vth can be found
