Find the voltage v1 and the currents I1 and I2 for the circuit shown. To solve this problem first find the total current going through the 14 ohm resistor. To do this find the effective resistance of ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

Two lamps connected in series with an open switch and a cell The circuit diagram shows a circuit with two lamps connected in series. If one lamp breaks, the other lamp will not light. The current is ...

Designs that need to measure small signals riding on high-voltage power rails suggest the use of isolation devices. However, a high-common-mode-voltage instrumentation amplifier used with a ...
