Proportion of Voltage to Resistance in a Series Circuit
Proportion of Voltage to Resistance in a Series Circuit

... The total resistance, RTotal, of a series circuit is found by adding up the resistance values of the individual resistors. A single voltage, Vs, can be measured across each resistor. There exists a very important relationship between voltage and resistance: In a series electrical circuit with multip ...

Then we go through R1 from the low V side to the high V side (since we are moving against the current flow I1): a voltage rise so the change is +I1R1. Finally, we go through R2, in the same direction as the current I2, so we have a voltage drop and ...

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.
