I have a relay circuit powered by a 9V battery. The best available relay selection is 6V, 60mA (100Ω) that draws 90mA @ 9V. What options do I have? Add a 200Ω series resistor. Resulting voltage and ...

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the basics.

The current flowing in a series circuit is the same everywhere. Figure caption, A series circuit with two bulbs and one cell. The ammeter will read the same at points 1, 2 or 3. In series circuits ...

Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. We can calculate the voltage, current and resistance in these circuits.

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

However, this is a great time to look at the difference between series and parallel circuits. A Simple Circuit. Just about the simplest circuit you can create uses just one battery and one light bulb.

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India ...
