The total resistance of the circuit increases. hence the new resistance after adding the resistance will be
new resistance = old resistance + added Resistance
There is a small mistake in the question. The second word is 'changes' not 'charges'
When more devices are added to a parallel circuit, the total circuit resistance goes down.
RPARALLEL = 1 / Summation1toN (1 / RN)
What happens to the circuit resistance when more devices are added in parallel circuit, the total resistance is going to reduce from the formular
Rtotal=R1*R2*. . . . *Rn/R1+R2+. . . > +Rn
No, as the number of branches in a parallel circuit increases you will have more paths for current to travel on.
1/( 1/R1 + 1/R2 + 1/Rn )
1/( 1/10 + 1/10 ) = 5 ohms
1/( 1/10 + 1/10 + 1/10) = 3.33333 ohms

Resistors in a parallel circuit measuring voltage voltmeter
In that case, the equivalent (total) resistance will decrease.
The amount of current that flows in a circuit is proportional to the voltage and inversely proportional to the resistance, as per Ohms law (I=V/R) where I is current.When resistances (IE loads) are connected in series, the total resistance is the sum of the loads (IE Rtotal = R1 + R2 + R3 ...)When they are connected in parallel, the total resistance is the inverse sum of the reciprocals of each resistance (IE 1/Rtotal = 1/R1 + 1/R2 + 1/R3 ...)Therefore in parallel the total resistance is much lower, and therefore at the same voltage more current will flow.
In brief, the overall or net resistance changes and the resistors in series and/or parallel can be represented by a single equivalent resistor. If you consider series resistors the equivalent resistance of the series would be: R = R1+R2+ ... +Rx The equivalent resistance of parallel resistors would be: 1/R = 1/R1 + 1/R2 + ... + 1/Rx One rule to always remember when dealing with series and parallel resistors is the voltage across each resistor in parallel will be the same as defined in Kirchhoff Voltage Law and the current across each resistor in series will be the same by Kirchhoff Current Law.

Of course. Additional resistors change total resistance, which changes current, which affects power.
ALL resistance are conductors. just the magnitude value changes
Yes and no. As voltage changes, current changes, causing power to change, with the end result that temperature changes. Most resistors have a small temperature coefficient, so their resistance will change slightly as the voltage changes.
Heat changes the resistance of a circuit. The change is detected by the system, and activates the alarm.

The resistance value for linear resistance is changed by changing the wavelength of the current or by installing additional resistors in the circuit. This restricts the amount of electricity which flows through the wiring.The resistance value for the linear resistance can be changed through strain over time. It can also be changed by changes in temperatures, such as going from hot to cold.
Total resistance decreases:1/R(total) = 1/R1 + 1/R2 + 1/R3Assuming each lightbulb has the same resistance: R1 = R2 = R31/R(total) = 1/R = 1/R + 1/R = 3/RR(total) = R/3Before the bulb was added:1/R(total) = 1/R + 1/R = 2/RR(total) = R/2R/3 < R/2
The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.
The force that changes is air resistance and the force that stay the same is gravity.
genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects.
