A 100-ohm resistor is commonly used in various electronic applications to limit current flow, divide voltage, or match impedance in circuits. It may be employed in signal conditioning, where it helps protect sensitive components by preventing excessive current. Additionally, in audio applications, a 100-ohm resistor can be used for termination to minimize reflections and ensure signal integrity. Its specific value is chosen based on the desired electrical characteristics and the requirements of the circuit design.

If you have three 100 ohm resistors, and you want an equivalent resistor of 66.7 ohms, put two resistors in series, and then parallel the third resistor across the first two. Resistors in series: R1 + R2 Resistors in parallel: R1 * R2 / (R1 + R2) This example: Two 100 ohm resistors in series: 100 + 100 = 200 A 100 ohm resistor in parallel with a 200 ohm resistor: 100 * 200 / (100 + 200) = 66.7
You need to calculate the equivalent resistance. For instance, if the three resistors are connected in series, simply add all the resistance values up. Then, you calculate the current (in amperes) using Ohm's Law (V=IR); that is, you need to divide the voltage by the resistance.

Yes, a 47 ohm resistor can be used in place of a 47E resistor, as "47E" typically denotes a 47 ohm resistor where "E" represents ohms in certain notations. However, ensure that both resistors have similar power ratings and tolerances for optimal performance in your circuit. Always double-check the specifications to ensure compatibility with your application.

100 megohm the 10 ohms completely vanishes in the tolerance of the 100 megohm resistor, in that range tolerances can exceed 20% of nominal.
Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms. The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.

The current would be about 20 volts.

No, a 2.2k ohm resistor and a 220 ohm resistor are not the same resistance. The "k" in 2.2k ohm stands for "kilo," which represents a multiplier of 1000. Therefore, a 2.2k ohm resistor is equivalent to 2200 ohms, while a 220 ohm resistor is simply 220 ohms. The difference in resistance values is a factor of 10 due to the kilo prefix.
