Which direction does a resistor go?

If I understand your question, then yes - resistors are reversible, in the sense that they can be connected to the circuit in either direction. Resistors are not like diodes or capacitors. They do not have a polarity. The conduct (or resist) current equally in both directions of current flow.

How do you read the value of a resistor?

  1. Position the resistor with the gold or silver color band to the right..
  2. Read the color sequence that must be decoded to determine resistance.
  3. Determine the coded number for the resistive value.
  4. Determine the tolerance of the resistor.
  5. Determine the decoded number for the resistive value.
  • What are the colors of resistors?

    Components and wires are coded with colors to identify their value and function. The colors brown, red, green, blue, and violet are used as tolerance codes on 5-band resistors only. All 5-band resistors use a colored tolerance band.

How do you check a resistor with a multimeter?

  1. Remove power from the circuit containing the resistor.
  2. Isolate the resistor from the circuit.
  3. Inspect the resistor.
  4. Read the resistor value visually.
  5. Prepare a digital multimeter (DMM) to measure the resistor.
  6. Measure the resistance.
  7. Determine the actual resistance of the resistor.
  • How do you test a capacitor with a multimeter?

    To test the capacitor with a multimeter, set the meter to read in the high ohms range, somewhere above 10k and 1m ohms. Touch the meter leads to the corresponding leads on the capacitor, red to positive and black to negative. The meter should start at zero and then moving slowly toward infinity.
  • How do you measure resistors?

    Method 1 Measuring Resistance with a Digital Multimeter
    1. Choose the item whose resistance you wish to measure.
    2. Plug the test leads into the correct test sockets.
    3. Turn on the multimeter and select the best testing range.
    4. Touch the multimeter leads to the ends of the component you are testing.
    5. Turn off the multimeter.
  • What is the symbol of continuity in a multimeter?

    Set the multimeter to 'Continuity' mode. It may vary among DMMs, but look for a diode symbol with propagation waves around it (like sound coming from a speaker). Now touch the probes together. The multimeter should emit a tone (Note: Not all multimeters have a continuity setting, but most should).

Do resistors have a positive and negative side?

Current in the drawing above is shown entering the + side of the resistor. Resistors don't care which leg is connected to positive or negative. The + means where the positive or red probe of the volt meter is to be placed in order to get a positive reading. This is called the "positive charge" flow sign convention.
  • Do you put a resistor on positive or negative?

    It depends if current is moving from negative to positive or positive to negative. (Sorry, it was another thread) In reality, no, it doesn't matter which side the resistor is on. The two components together make up a Series Circuit, and current is the same at all points, but voltage changes.
  • Do all capacitors have a polarity?

    The large, 20,000 µF electrolytic unit shown in the upright position has its positive (+) terminal labeled with a “plus” mark. Ceramic, mylar, plastic film, and air capacitors do not have polarity markings, because those types are nonpolarized (they are not polarity sensitive).
  • Which way does current flow from a battery?

    Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.
