... are also in parallel with the sensor. The sensor LEDs provide input voltage for two comparators on the LM339 chip with the variable resistor R2 providing a "dead zone" or sensitivity adjustment. Each comparator output is fed into a transistor Darlington pair which in turn drives the DC motor. The ra ...

... So far, we have only looked at series circuits. In a series, resistors are placed end-to-end so that electrons must flow through each resistor. Important Note: Current is exactly the same everywhere in a series circuit. The same amount of charge per unit of time passes through each point, as there i ...

Network analysis (electrical circuits)
A network, in the context of electronics, is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, every component in the network. There are many different techniques for calculating these values. However, for the most part, the applied technique assumes that the components of the network are all linear.The methods described in this article are only applicable to linear network analysis, except where explicitly stated.
