resistance. The current is the flow of electrons; the current is dependent on the amount of voltage‚ which is applied. Voltage is the push given to the current. The current has to go through a circuit‚ which contains resistance so if you increase that push you also increase the flow of the current. All materials have a slight resistance to electricity factors affecting the resistance are: Length‚ Voltage & Temperature and Surface Area Length The diagram shows the happenings of a wire the

© Rapid Electronics | An oscilloscope is a test instrument which allows you to look at the ’shape ’ of electrical signals by displaying a graph of voltage against time on its screen. It is like a voltmeter with the valuable extra function of showing how the voltage varies with time. A graticule with a 1cm grid enables you to take measurements of voltage and time from the screen. The graph‚ usually called the trace‚ is drawn by a beam of electrons striking the phosphor coating of the screen making

forms of AC waves. Waves are visual representations of the variation of a voltage or current over time and are used in many applications throughout technology. Aim The aim of this laboratory was to be able to measure the voltage in a circuit over a specific time using equipment such as an oscilloscope‚ and using it to look at the SINE wave that is generated‚ and also calculate the RMS voltage from the peak voltage and vice versa.

Symbol Uses of functions Galvanometer A galvanometer is a very sensitive meter which is used to measure tiny currents‚ usually 1mA or less. Ammeter An ammeter is used to measure current. Voltmeter A voltmeter is used to measure voltage. Resistor (Fixed and Variable) Fixed Variable A resistor restricts the flow of current‚ for example to limit the current passing through an LED. A resistor is used with a capacitor in a timing circuit. This type of variable resistor with

Checkpoint (p.197) 1. The heating effect of current increases with the applied voltage across the wire. Microscopically‚ when a voltage is applied across the ends of a metal wire‚ an electric field is set up between the ends. The free electrons are accelerated by the field and collide frequently with the metal ions in the wire. Thus‚ some energy is transformed into the internal energy of the wire. When the applied voltage increases‚ the electric field is stronger. The electrons collide harder as

The values also were shown clearly by the device. The last one‚ which is objective C‚ is to help us familiarize with the function generator and oscilloscope. The values for the first half were still clear but it seemed that the AC voltage differ hugely to the other voltages. While turning the position knobs to shift the cursors at either the peak or complete cycle of the wave‚ there formed the delta which has significantly agreed to the true value of what it measures. CONCLUSION I conclude that
