Transcript of Standard 4

Foundation of Electronics Norianna Ewald Volt·age
/voltij/ Voltage is the potential energy that pushes electrons around in which creates electrical current flow. Voltage is measured in volts. It is mistaken that voltage is measured in watts, but it is not. Watts are a unit of power equal to the work done at the rate of one joule per second. Current is the rate at which charge flows past a point on a circuit. The charge can be negative or positive. In order for a charge to flow, it needs a force to create the current, This force is voltage. Voltage is the pressure that pushes the current along and the conductor is the resistor. The conductor is called the resistance. Electrical resistance is the same thing as friction. Re·sist·ance
/rizisetns/ Cur·rent
/kerent/ In·duc·tance
/induktans/ Inductance is the property of an electric circuit in which an electromotive force is impelled in it as the result of a changing magnetic flow. Ca·pac·i·tance
/kəˈepasiteəns/ Capacitance is the ability to store an electric charge. All systems that are able to be charged by electricity exhibits capacitance. Alternating Current Vs Direct Current AC current DC current vs the direction always alternates flows in one direction Has higher voltage Has lower voltage Longer transmission line Shorter transmission line Frequency is 50 or 60hz depending on the country Frequency is 0, Ohm's Law Ohm's Law states that the electric current that passes through a conductor is in direct proportion with the potential difference across it. Kirchhoff's Laws Circuit Laws Voltage Laws Kirchhoff's law states that the sum of all emfs and voltage drops is equal to zero Kirchhoff's current law The sum of the voltage gains and drops around any closed circuit is zero Soldering Soldering is put two pieces of metal together by applying heat and melting a third metal or alloy into the joint. This third metal must melt at a lower temperature than the metal being soldered and be able to attach to the surfaces being joined. Analog An analog system is circuit variable system. Unlike other circuits, it has continuous time voltages and currents. Digital Circuit A circuit designed to function at input voltages at one of a finite number of levels.
