20.1 Series and Parallel Circuits #1
... A parallel circuit has at least one point where the circuit divides, creating more than one path for current. Each path is called a branch. The current through a branch is called branch current. If current flows into a branch in a circuit, the same amount of current must flow out again, This rule is ...

AC vs. DC
... Answer Electricity can be generated as either AC or DC, but AC allows us to change the Voltage Current ratio in order to save money (This cannot be done with DC). The full explanation... Electricity has to travel a long distance through wires to reach your home To transmit the electrical e ...

A Zero-Sequence Voltage Injection-Based Control
... One of the main technical challenges associated with the control of a PHMMC-HVDC system is to simultaneously control the dc current/power flow and the real and reactive power. The existing method proposed to resolve this issue is based on third harmonic component injection where a third harmonic com ...

DC Series Versus Parallel Circuits
... Measure and record the total voltage for the entire span of three resistors by touching one probe before the first resistor and the second probe after the third resistor. Measure and record the current through each resistor. To do so: o Disconnect the negative end of the resistor from the line and a ...

THEVENIN THEOREM
... The Thevenin voltage is the voltage between a and b with the load removed. Follow the path of current leaving the source to see if it divides and it goes through the 40 Ohms resistor. Note that no matter if you have resistors on the open terminals since no current can flow through them. In this case ...

... When the switch is closed or opened, the switch contacts bounces against each other before settling. Sometimes the microcontroller picks this up as bouncing noise. This could lead to undesirable conditions. For example the microcontroller may receive multiple triggers even when the button is pressed ...

Variable resistance
... The diode in this activity emits light as electricity flows through it. The higher the electrical current, the brighter the light. However, too much current will cause the conducting material inside the diode to burn up, destroying the LED. What is needed is a simple way of controlling the amount of ...

Electrical ballast
An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
