Vtotal = V1 = V2 = V3 So if three 2V cells are connected in parallel with each other the potential difference supplied to the circuit is 2V. Resistors in series and in parallel Resistors in Series When resistors are in series with each other there total resistance is just there individual resistance added together. Resistors in parallel When resistors are in parallel with each other there total resistance is found using the equation below. Current in series and parallel circuits

Oscillators and timers Introduction The NE555 chip which operates at 5v‚ utilizes two comparators for temperature stability. This chip is capable of producing oscillations. It is made up of 8 pins and its oscillation mode is controlled by two resistors and a capacitor. Each pin is set to perform a function. Pin 1 serves as ground. Pin 2 is the trigger - the input to the lower comparator which sets the latch that causes output to go high. Pin 3 serves as the output.

low DC voltage is applied at the feeder end through a series resistor. The current would vary depending upon the length of fault of the cable in case there is a short circuit of LL or 3L or LG etc. The series resistor voltage drop changes accordingly which is then fed to an ADC to develop precise digital data which the programmed microcontroller would display the same in Kilo meters. The project is assembled with a set of resistors representing cable length in KMs and fault creation is made

Pilot trolley method for trains AIM: To design a auto pilot trolley method for trains. Base Technology: EMBEDDED Abstract: It is a very useful project. By using this we can reduce the more train accident. The trolley is communicating with the train using ISM based RF signal. 432.92 MHz frequency signal is used for communication. As we do the project we use this frequency. It will sense the object using the IR signal‚ bomb is detected using metal detector‚ track open is sensed using limit

can determine the current through a resistor by measuring the voltage on both sides of the resistor‚ calculating the difference and dividing it by the resistance the resistor. The resistance that is measured is usually written on the side of the resistor or on the box that it comes in. The resistance of a resistor can also be determined by the number‚ color‚ and order of stripes on the side of it. That is the most common way of identifying a type of resistor. It is also available from the circuit
