Of course. Additional resistors change total resistance, which changes current, which affects power.

When do resistors short?
A; occasionally resistors short out especially at hi frequency hi voltage due to external contamination. But usually resistors open up or change to a hi value due to power overstress
How is the resistor behaved at high frequency?
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]
Where does the energy come from to amplify the signal in a amplifier?
The energy comes from an additional power source, like a battery. Via various resistors and capacitors, the energy from the power source is put into the circuit. The signal that enters the ciruit will exit the circuit with a higher energy; the signal has been amplified.
When resistors are connected in series then what happens to the watt?
Resistors are rated in wattage so the lowest wattage rating will be the wattage of the series circuit. It will be able to handle that power any more and the lowest wattage resistor could be damaged and fail.Another AnswerWhen two or more resistors are connected in series, the resistor with the lowest resistance will operate at the highest power. If the power developed by a resistor exceeds its rated power, then the resistor may burn out.
What does 1-4W and 1-8W means for resistors and do they affect the value of the resistor?
I think you mean 1/4W and 1/8W ratings for resistors. If so, it indicates wattage (power dissipation) ratings for resistors. Basically this specification for resistors shows maximum power that can be allowed to dissipate in the resistor. Wattage does not as such affect the value of resistor (it should remain with in % tolerance value specified when operated within specified wattage). ( P=I^2 x R). or (P = I x V) P=Power, I = Current, R= Resistance, V = Voltage Once you know the power rating, you can calcutate how much current can be passed through a resistor of specific value without causing a damage to the component or circuit. For long term reliability always it is advisable to design with a margin (for 1/4W or 250mW e.g. design so that it is always certain % less than the rated e.g. operate at 200mW or less) - Neeraj Sharma
Do additional resistors affect current in a series circuit?
Yes, additional resistors affect current in a series circuit by increasing the total resistance, which decreases the total current.
How does temperature affect power rating of carbon resistors?
Its normal power rating is at room temperature. For a temperature of 75 degrees, halve the rating.
Why are resistors called resistors?
Resistors have resisting power(resists the electric power).Due to having the resistive property, the name resistor is given to such electrical device.
How much power does a string of 6 4.5v 40ma led's consume?
The total power of a series of resistors is equal to the sum of the power dissipated by individual resistors. In this case, each resistor consumes 4.5v*.04amps which is equivalent to 1.08 watts. Since there are 6 resistors, 6.48 watts of power are consumed.
Five series resistors each dissipate 50 mW of power What is the total power?
AS:total power = P1 + P2 + P3 + .......so,total power = 5(50mW)= 0.25Wtotal power dissipated by the five resistors is 0.25W.
Does power decrease when adding resistors in parallel circuit?
no
Explain how the tolerance of various resistors affect the reliability of a digital circuit?
Hahn.
What is the resistors for?
the answer is that it is allowed to get the electricity right and it has energy power saver
What are the types of resistor?
There are many types of Resistors , which can be classified in many ways. The fundamental classification is based on the Power Handling Rating , which breaks up into Power Resistors & Low power resistors. Power Resistors can handle large Powers & Currents. These are generally made of High Resistance alloys like Nichrome , which are used in heaters , toasters etc. Some types of small power resistors are also used in electronic circuits which handle large currents like in power supplies etc. Infact the incandescent lamp is a special form of power resistor. Low power resistors are usually used in electronic circuitry , which again have different power capacity ratings usually less than 1watt to small surface mounted devices which are rated for few tenths of milliwatts. Another important classification is based on the stability of the resistor material & hence its ohmic values. Such resistors are used for precision applications like measuring circuits , meters etc. Then there are specialised forms of clasification depending on application e.g Positive & Negative Temeprature coefficient resistors ( Thermistors ) are used for temperature sensing , Voltage Dependent resistors are used in protection circuitry, High Voltage resistors are used where requires for high voltage ( kilovolts ) electronic circuitry like X Ray , Laser & Electrostatic Power supplies.
What does resistro do?
resistors is a most common electronic component and is used to control the voltage and current in a electronic circuit. resistors is inversely proportional to amount of power supplied,given by (power= voltage *current).
