when in series you can use this: R1+R2+R3+enz=you total resistance.

and when in parallel you can use this: Req = 1 / (1/R1+1/R2+1/R3+1/R4+enz).

If there are 2 resistors in parallel, use Product over sum: Req = R1*R2/(R1+R2).

For 3 resistors, a little more tricky: Req = R1*R2*R3/(R1*R2 + R1*R3 + R2*R3). For more than 3, use the general formula above for a quantity of resistors in parallel.

How does voltage and resistance behave in a series and a parallel circuit?

The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.


What type of circuit has little to no resistance and will usually blow a fuse?

there are three types of circuits. Series,parallel,parallel-series. Series circuits usually are involved with dimming lights, and blown fuses.


What two circuits one series and one parallel use light bulbs to provide resistance. Both circuits have the same number of light bulbs?

Series circuit gives higher resistance compared to parallel circuit.


What are the differences between series and parallel circuits in terms of their configurations and electrical properties?

In a series circuit, components are connected in a single path, while in a parallel circuit, components are connected in multiple paths. In terms of electrical properties, series circuits have the same current flowing through all components, while parallel circuits have different currents flowing through each component. Additionally, in series circuits, the total resistance is the sum of individual resistances, while in parallel circuits, the total resistance is less than the smallest individual resistance.

Made up of series and parallel circuits?

Almost everything is arranged in that way. Housing electricity is arranged with almost only parallel circuits so they can have the same voltage everywhere But if you need not 100, 120 or 127 Vac in some point, you put a resistance in series to where you need another voltage. In this way the voltage is consumed by that resistance and lowed to the desired level. You have to calculate the resistance first. Almost every electronical circuit has series and parallel and in macro scale, almost every device has 100, 120, 127, 200, 208, 220, 240 needs so you dont need a resistance to absorb power and all terminals in the building has the same or two of them at least.


How do series circuits and parallel circuits compare?

In series circuits, the current flows through each component sequentially, so if one component fails, the entire circuit will fail. In parallel circuits, each component has its own separate branch, so if one component fails, the others will continue to operate. Additionally, the total resistance in a series circuit is the sum of individual resistances, while in a parallel circuit, the total resistance is less than the smallest individual resistance.


Why dont series circuits shine as bright as parallel circuits?

By connecting components in series, you are increasing the equivalent resistance (known as thevenin resistance) of the circuit. Power is equivalent to Voltage^2 / Resistance. Therefore, by increase the resistance, you are decreasing the amount of power provided by the source.


Are parallel circuits like series circuits?

They are not exactly the same. A series circuit is one complete circuit with not other pathways. A parallel circuit is a complete circuit with multiple pathways . The resistance of a parallel circuit is completely different from the resistance of a series circuit. Therefore, this affects the voltage and the current produced,


Formula for inductance of series circuits?

AnswerInductances add in series, so the formula is simply L=L1+L2. Inductance is handled in the same manner as resistance in serial and parallel circuits.
