Yes
When an extra globe is added to a circuit, the total resistance depends on how the globes are connected. If they are connected in series, the total resistance increases because the resistances add together. If they are connected in parallel, the total resistance decreases, as the overall resistance is reduced by the additional path for current flow. Therefore, the change in total resistance depends on the configuration of the globes in the circuit.
If one branch of a parallel circuit has high resistance, it will draw less current compared to branches with lower resistance. This means that most of the total current will flow through the lower-resistance branches. Consequently, the voltage across all branches remains the same, but the overall current provided by the power source will be affected, potentially resulting in decreased total current in the circuit.
Voltage divided by total resistance will give the current. The resistance is simply the sum of all the individual resistances.
In a parallel circuit, the total resistance decreases because the total current can flow through multiple pathways; adding more branches allows for more current to bypass each resistor, effectively lowering the overall resistance. Conversely, in a series circuit, capacitance decreases because the total capacitance is determined by the reciprocal of the sum of the reciprocals of individual capacitances. This means that as more capacitors are added in series, the total capacitance approaches zero, as they each must charge to the same voltage, limiting the total charge storage capability.
If the overall load consists of:'R' = resistance of each individual resistor'S' = number of resistors in each series row'P' = number of series rows connected in parallel,then the effective overall DC resistance of the entire network is[ R S / P ]
When resistors are connected in parallel to the same voltage source, the overall resistance in the circuit decreases. This is because the current has multiple paths to flow through, reducing the total resistance that the current encounters.
Resistors connected in parallel have the same voltage across them, while resistors connected in series have the same current passing through them. In a parallel configuration, the total resistance decreases as more resistors are added, while in a series configuration, the total resistance increases.
Yes, the current split in parallel circuits does affect the overall resistance in the circuit. In a parallel circuit, the total resistance decreases as more branches are added because the current has multiple paths to flow through, reducing the overall resistance.

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.

The total resistance in a circuit with series resistors is the sum of the individual resistances. When more resistors are added in series, the total resistance increases because the current has to pass through each resistor, making it harder for the current to flow.
In a parallel circuit, the total resistance decreases because the total current can flow through multiple pathways; adding more branches allows for more current to bypass each resistor, effectively lowering the overall resistance. Conversely, in a series circuit, capacitance decreases because the total capacitance is determined by the reciprocal of the sum of the reciprocals of individual capacitances. This means that as more capacitors are added in series, the total capacitance approaches zero, as they each must charge to the same voltage, limiting the total charge storage capability.
In a series circuit, the total resistance increases because the individual resistances add up. As the current flows through each component in succession, the resistance offered by each component adds to the total resistance. This leads to an overall increase in resistance in a series circuit.
If the overall load consists of:'R' = resistance of each individual resistor'S' = number of resistors in each series row'P' = number of series rows connected in parallel,then the effective overall DC resistance of the entire network is[ R S / P ]
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.
