Circuit designs usually tell you the safe resistor tolerance to use, whether for each individual resistor or for all the resistors in the circuit. Look for a notation in the parts list or as a footnote in the circuit diagram. If the schematic doesn’t state a tolerance, you can assume it’s okay to use standard-tolerance resistors (+/–5% or +/–10%).

How can we control voltage using resistor

Connecting resistors in series like this across a single DC supply has one major advantage, different voltages appear across each resistor producing a very handy circuit called a Voltage Divider Network.

Is there any way to adjust variable resistor automatically?

Then, since there is a parallel circuit, arduino will get the same voltage as the 10k(ohm) resistor. So this LDR resistor does the function of a pull-up resistor which draws the current to VCC. So this LDR resistor does the function of a pull-up resistor which draws the current to VCC.

Resistors in Series and Parallel Combinations

However, by only connecting two pins (one outside pin and one center pin) of a potentiometer to your circuit, you can turn a pot into a variable resistor. Think about it this way: the potentiometer is filled with resistive material and turning the knob changes the amount of this material that the electrons must travel through before leaving the pot. This means that the maximum resistance of

How to give connections to a rheostat Quora

21/04/2011 · Hi, I have got a dual gang potentiometer connected two circuits, where in circuit 1 it's called R1 and in circuit 2 it's called R2. What I would like to do is to have R1 decreasing while increasing R2 with the same amount of resistance, by turning the knob of the potentiometer. I was wondering if anyone know how it can be connected?

how to catch mullet on line

Well, here's a tip from Greg James' fishing history book that he used to great effect when working as a deckie for a couple of commercial line fishermen out of Thevenard on the State's far west coast. Run up to 1 metre of line below a round or barrel sinker & attach both (yes, both) hooks below that weight. Mushy & very soft squid is a great bait to use with this technique.
