demonstrating how to perform CPR. CPR is a combination of chest compressions and ventilations. You only perform CPR on a patient that is unconscious‚ not breathing‚ and has no pulse. These are signs of cardiac arrest. The first step is to size-up the scene‚ making sure it is safe for you‚ the patient‚ and any bystanders. The second step is to perform an initial assessment of the situation. To check if the patient is breathing tilt their chin up to open the airway and then put your

familiarization of electrical apparatus. Name Image 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

ELECTRICAL CONDUCTORS A conductor is an object or type of material which permits the flow of electric charges in one or more directions. For example‚ a wire is an electrical conductor that can carry electricity along its length. Physics All conductors contain electrical charges‚ which will move when an electric potential difference (measured in volts) is applied across separate points on the material. This flow of charge (measured in amperes) is what is meant by electric current. In most

It is very obvious from the comments posted in this thread that the people driving the use of the RaspberryPi as a PLC training tool have not conducted any professional‚ electrical and electronic engineering research into the design criteria required for an educational PLC or are prepared to acknowledge the legally required European Union safety compliance to IEC61508 and IEC 611313. A PLC’s functional criterion is an industrial control device used to automate electrically driven machinery

Electrical Cable Cross section is just a two-dimensional view of a slice through an object. An often asked question: How can you convert the diameter of a round wire d to the circle cross section surface or the cross-section area A (slice plane) to the cable diameter d? Resistance varies inversely with the cross-sectional area of a wire. | ------------------------------------------------- Top of Form | Wire diameter d | unit | | | Cross-sectional area A | unit2 | | |

Electrical Charges: Electrical charges come as plus or minus. Like charges repel‚ unlike charges attract. Electrons and protons have‚ to fantastic accuracy‚ equal and opposite charges. Quarks have 1/3 the electron charge but are never seen alone! In wires electrons do the moving to carry electrical current. In solutions or plasmas there can be positive charge carriers‚ ions or protons. Although the signal to tell electrons to move in wires travels at about 2/3 the speed of light
