Adding any additional element in parallel will reduce the combined resistance. Do some sample calculations to get a "feel" for this: Total resistance (R) is calculated as 1/R = 1/R1 + 1/R2 + 1/R3... In other words, take the reciprocal of the individual resistances, add them, and then take the reciprocal of the result.

What happens to a parallel circuit resistance if the voltage applied is doubled?
That has no effect on the resistance. The current doubles also.
What is the equivalent resistance through the entire circuit?
The equivalent resistance is the overall effect all of the resistances in a circuit has. Put another way, it is the value a single resistor in a circuit would have to be in order to have the same effect as all of the resistors resistors combined in a given circuit.
What would be the effect of adding a load in parallel to a parallel circuit?
Ohm's Law says Voltage = Current x Resistance With constant voltage, an increase in resistance decreases the current. Now the load can be added in two basic ways. If the load is added in series the resistance will increase. If you add load in parallel the resistance will decrease and the current will increase from the source.
There are 2 light bulbs in a circuit wired in parallel a third light bulb is added in parallel what is the effect on total resistance of addin the third bulb?
The total resistance of the original light bulbs are: 1/(1/R1 + 1/R2) The total resistance after the addition of the third light bulb is: 1/(1/R1 + 1/R2 + 1/R3) Therefore, if the resistance of the third light bulb is not infinity, 1/R3 will be greater than 0 and and adding a greater-than-0 number to the denominator of a fraction will lower the value of the fraction. Therefore, the total resistance will lower. Intuitively, you can think that adding a third bulb is opening up another possible path for electrons to flow through, therefore decreasing total impediment to electron flow.
What happens in a parallel circuit when a component breaks?
This depends if the component was wired in series or in parallel to the rest of the circuit. When a component breaks, it stops functioning and cannot conduct electricity. If it is wired in series to the rest of the circuit, the entire circuit will cease functioning. If it is wired in parallel to the rest of the circuit, the circuit will continue functioning, but with more electricity going to the other line.

What happens to a parallel circuit resistance if the voltage applied is doubled?
That has no effect on the resistance. The current doubles also.
Why a circuit will produce a loading effect?
This happens because the total parallel resistance is lower than the individual resistors that make up the group of parallel resistors. When you add another parallel load, the resistance of that parallel group lowers and as result increases the current for the rest of the circuit.
What is the equivalent resistance through the entire circuit?
The equivalent resistance is the overall effect all of the resistances in a circuit has. Put another way, it is the value a single resistor in a circuit would have to be in order to have the same effect as all of the resistors resistors combined in a given circuit.
What is the effect on total resistance of adding this third bulb?
If a fourth bulb were added in a similar way to the three existing bulbs, the resistance in the circuit would go up if the bulbs were series connected, and it would go down if the bulbs were parallel connected.
What is the affect of a series circuit on current?
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .
In a series circuit each device that is added to the circuit decreases the?
Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.

What happens to the current in circuit as the resistance increases?
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
Can inserting a resistor in a circuit have an effect similar to an short circuit?
It creates an extra load to the circuit if placed parallel to other circuits. this load approaches the equivalent of a short circuit as the resistance value placed there reduces.
