How to select electronic components?
- Manufacturers.
- Application Circuit Complexity.
- Electrical Parameters [voltage, current, power, accuracy, response time, speed, resolution, etc.]
- Mechanical Parameters [dimension, package, weight, etc.]
- Consideration w.r.t Manufacturing / Testing.
How do you determine the value of a capacitor?
The voltage rating of the capacitor should always be at least 1.5 times or twice the maximum voltage that it may encounter in the circuit. Capacitors are not as reliable as resistors. They get easily damaged once the applied voltage nears their maximum rating.
Does it matter where the resistor goes in a circuit?
It doesn’t matter! The resistor can go before – or after – the LED, and it will still protect it. the current that flows out of a battery is always equal to the current that flows back into the battery.
How do I know if my electronic component is replacing?
- Spread some of the electronic devices on a piece of paper on your table or desk.
- With the naked eye observe the appearance and shape of the devices.
- Examine each device with a hand lens magnifier.
- Use a microscope or stereoscope to look for details, especially on the transparent.
How do you convert a capacitor to a value?
The capacitor conversion chart below reveals the equivalents between µF, nF and pF in an easy to use table format….Capacitor conversion chart.

|---|---|---|
| microfarads (µF) | Nanofarads (nF) | Picofarads (pF) |
| 0.00001 | 0.01 | 10 |
| 0.0001 | 0.1 | 100 |
| 0.001 | 1 | 1000 |
How do you know which way a resistor goes?
Always read resistors from left to right. – Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5\% or 10\% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.
How do you know when a circuit is completed?
For an electronic circuit, the matter carried is the charge by electronics and the source of these electrons is the positive terminal of the voltage source .When this charge flows from the positive terminal, through out the loop and reaches the negative terminal, the circuit is said to be completed.
How do you find the total components in a series circuit?
Components in a series circuit share the same current: I Total = I 1 = I 2 = . . . I n; The total resistance in a series circuit is equal to the sum of the individual resistances: RTotal = R 1 + R 2 + . . . R n; Total voltage in a series circuit is equal to the sum of the individual voltage drops E Total = E 1 + E 2 + . . . En
What are the active components of a circuit?
They can be linear components with a linear response to the electrical energy or nonlinear components with a nonlinear response to the electrical energy. One which supplies energy or controls the flow of energy. These are the Active components.
How do you choose a capacitor value for an RC circuit?
You choose a capacitor value by using the RC time constant: This constant gives you the time it takes for a voltage in an RC circuit to go from 0\% to 63\% of its full value. You can use this time constant to calculate the cutoff frequency in a filter, or just how long a delay will be in a blinking light circuit.
