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.
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
If the number of receivers in a circuit increases, the overall current can be affected depending on how the receivers are arranged. In a parallel circuit, adding more receivers generally decreases the total resistance, which can increase the overall current if the voltage remains constant. In a series circuit, adding more receivers increases the total resistance, leading to a decrease in overall current. Therefore, the effect on current depends on whether the receivers are connected in series or parallel.
This is a very technical electrical question that may be difficult to understand without further study. But adding appliances to an outlet is the same as adding resistance in parallel. Adding resistance in parallel, the resistance of the circuit goes down. That is why you get more current flow. By contrast, adding resistance in series increases the resistance of the circuit and therefore reduces current, all else being equal.
If the circuit consists of resistors only, you simply add the values of all the resistors, in ohms.
In a series circuit, the total resistance is the sum of the individual resistances of each load. This means that if you have multiple resistors (or loads) connected in series, you can calculate the total resistance by simply adding their resistances together: ( R_{total} = R_1 + R_2 + R_3 + \ldots ). Each load's resistance contributes to the overall resistance, affecting the current flow through the circuit. The voltage across each load can vary depending on its resistance, following Ohm's Law.
Total resistance decreases.
reduces it from 1/2 to 1/3rd
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.
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.
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 .
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
To find the net resistance of the circuit connected to the battery in the figure, you need to calculate the total resistance by adding up the individual resistances in the circuit.
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
If the number of receivers in a circuit increases, the overall current can be affected depending on how the receivers are arranged. In a parallel circuit, adding more receivers generally decreases the total resistance, which can increase the overall current if the voltage remains constant. In a series circuit, adding more receivers increases the total resistance, leading to a decrease in overall current. Therefore, the effect on current depends on whether the receivers are connected in series or parallel.
Many circuits have safety devices such as fuse. A fuse contains a substance that melts if it gets hot. if a short circuit happens, the heat causes the fuse to melt. The circuit is broken. because the current stops ,no damage is done.
