Its main purpose is to slow down current surges or spikes by temporarily storing energy in an electro-magnetic field and then releasing it back into the circuit. Resistor The resistor is a passive ...

Some background on the basic principles ... fuses, and circuit breakers. In the case of analog gauges, the sending unit or “sender” is a variable-resistor contact switch to ground.

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire ... cabling. The circuit in question.

With the shunt resistor modified, which can be done with either a bypass resistor or a custom circuit board, the only other change is to upgrade the 100 A fuse near the battery for a larger size.

Using properties of a series circuit, the sum of the voltages across the LED and resistor R must equal the supply voltage. \({V_s} = {V_{LED}} + {V_R}\) Now substitute the supply voltage (\(6V ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in ...
