What happens to the effective resistance of a circuit when additional resistors are added in parallel resistors already present?
When additional resistors are added in parallel to existing resistors in a circuit, the effective resistance decreases. This is because parallel resistors provide multiple pathways for current to flow, which reduces the overall resistance. The total or equivalent resistance ( R_{eq} ) can be calculated using the formula ( \frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \ldots + \frac{1}{R_n} ), indicating that adding more parallel resistors results in a lower ( R_{eq} ).
What are some series circuit questions?
Some common questions about series circuits include: How does voltage divide across components in a series circuit? What happens to the total current when more resistors are added? How does the total resistance change with additional components? Additionally, how do series circuits affect the overall power consumption compared to parallel circuits?
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.
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.
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.
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.
Does power decrease when adding resistors in parallel circuit?
no

Three equal resistors connected in series across a voltage source dissipate a power of 10W what sould be the power desipated if same resistors are connected in parallel?
If three equal resistors are connected in parallel, the equivalent resistance will be one-third of the resistance in series. This lower resistance will result in a higher current flowing through the resistors when connected in parallel compared to when they are in series. Therefore, the power dissipated by the resistors in parallel will be greater than 10W.
