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 2 contacts (a rheostat) is usually used to control current.. Capacitor: (fixed & variable) Fixed Variable A capacitor stores electric charge. A capacitor is used with a resistor in a timing circuit. A variable capacitor

What is Telecommunication? Many people call telecommunication the world’s most lucrative industry. If we add cellular and PCS users‚ there are about 1800 million subscribers to telecommunication services world wide (1999). Annual expenditures on telecommunications may reach 900‚000 dollars in the year 2000. In industrialized nations‚ the telephone is accepted as a way of life. The telephone is connected to the public switched telecommunications network (PSTN) for local‚ national

is focused almost entirely on several different aspects and uses of pointers. The lab also introduces pointer arrays and pointers to pointers. The Resistor class created in the Week 2 lab will be used as the class that the pointer operations will be used upon. The lab also requires the use of accessor functions and static data members‚ which may need to be added to the Resistor class definition and implementation. Deliverables | 1.

equations are true of a set of resistors in series. The current is the same in all of the resistors and the connections between them. I_in= I_12= I_23= I_out (1) The voltage across the whole set is equal to the sum of Voltages across each individual resistor. V_eq=V_1+V_2+V_3 (2) The resistance of the connected set is equal to the sum of the resistance of each resistor. The equivalent resistance acts as one single resistor. R_eq=R_1+R_2+R_3

expecting our experimental graph to provide us a straight line. Current Vs. Voltage There are two types of resistors in the circuit; they are series and paralllel connections. Series connection In series connection‚ the current flows through each resistor is the same. There is only one path for the current to pass through. The voltage drop is proportional to the resistance of individual resistors. Rtotal is larger than any of the individual R. Parallel connection In parallel connection‚ the
