Film resistors have lower noise than carbon resistors.
I observe that the total effective resistance of several resistors in series is the sum of the individual resistance values of the individual resistors.
It depends upon the connection of the resistors, if the resistors are connected in parallel then the voltage is same where as in case of resistors connected in series the voltage is different across different resistors.
If a short occurs in a resistor in series with other resistors, the voltage drops across the other resistors will increase. If a short occurs in a resistor in parallel with other resistors, the voltage drops across the other resistors will decrease, to zero.
The major problem with resistors at high frequencies is for wire-wound (power) resistors, that will act as inductors at high frequencies. In addition, very small resistors, like chip resistors, can also exhibit capacitive effects. Special high frequency resistors are designed to offset these effect.[1]
most of the resistors commonly used are carbon resistors
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
Film resistors have lower noise than carbon resistors.
Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.
Both resistors will have the voltage of the battery.
Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.
resistors are used to resist the flow of current in a circuit.......
Resistors are like funnels, they restrict the flow of current.
Linear resistors
Resistors are a material that resists the flow of electrons. The resistors are materials that resist electric current energy to be changed into other forms.
I observe that the total effective resistance of several resistors in series is the sum of the individual resistance values of the individual resistors.
photo resistors, or light dependent resistors, are devices with variable resistance, that cahnges depending on how much light is hitting the device
