How can you connect resistors to produce an equivalent resistance which is the same as the resistance of each individual resistor?
You can connect 4 resistors in series-parallel, i.e. two in series, both in parallel with another two, and the effective resistance would be the same as one resistor. Similarly, you can connect nine resistors in 3x3 series-parallel, or 16 resistors in 4x4 series-parallel, etc. to get the same resistance of one resistor.
What else can I help you with?
In what type of circuit will the equivalent resistance be less than the resistors in the circuit?
In a parallel circuit, the equivalent resistance is always less than the resistance of the individual resistors. This occurs because the total current can split across multiple paths, reducing the overall resistance. As more resistors are added in parallel, the equivalent resistance continues to decrease. This behavior contrasts with series circuits, where the equivalent resistance is the sum of all resistors and is always greater than any individual resistor.
What is the combined resistance of a 39k and a 47k resistor connected in series?
86k. Resistance in series is the sum of the individual resistors.
How do resistors act in series?
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.

Which has a highest resistance between shunt resistor and series resistor?
If you are placing more than one resistors in series, then its combined resistance is higher than when you place these resistors in shunt.
How to find Equivalent resistance when you have both parallel and series resistors?
To find equivalent resistance when you have both parallel and series resistors, start simple and expand... Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value. Repeat that process, effectively covering more and more of the circuit, until you arrive at a single resistance that is equivalent to the circuit. For resistors in series: RTOTAL = R1 + R2 For resistors in parallel: RTOTAL = R1R2/(R1+R2)
How does the effective resistance of four resistors in parallel compared to the individual resistance?
It depends on the values of the individual resistors. But if each resistor is identical, then the total resistance will be one-quarter that of an individual resistor.
In what type of circuit will the equivalent resistance be less than the resistors in the circuit?

What is the equivalent resistance of three resistor with 3 ohms connected in star?
There is no 'equivalent resistance' for three resistors connected in star.
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.

86k. Resistance in series is the sum of the individual resistors.

What is the formula for calculating the equivalent resistance of a series circuit?
Equivalent resistance of a series circuit is the sum of the resistance of all appliances. The formula is R=R1+R2+... where R is equivalent resistance, R1, R2 and so on is the resistance of the individual appliances.
Which has a highest resistance between shunt resistor and series resistor?
If you are placing more than one resistors in series, then its combined resistance is higher than when you place these resistors in shunt.
How does the area of series resistors affect the overall resistance in a circuit?
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.
How to find Equivalent resistance when you have both parallel and series resistors?
To find equivalent resistance when you have both parallel and series resistors, start simple and expand... Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value.

For resistors in series: RTOTAL = R1 + R2 For resistors in parallel: RTOTAL = R1R2/(R1+R2)
Which has more resistance three resistors in series orf three resistors in parallel?
Three resistors in series have a higher total resistance than three resistors in parallel. In a series configuration, the total resistance is simply the sum of the individual resistances (R_total = R1 + R2 + R3). In contrast, for resistors in parallel, the total resistance is less than the smallest individual resistor and is calculated using the formula 1/R_total = 1/R1 + 1/R2 + 1/R3. Therefore, series resistors result in greater resistance compared to parallel resistors.
How is the stepped resistor differ from the fixed resistor?
A stepped resistor, also known as a variable resistor or rheostat, allows for adjustable resistance levels, enabling fine-tuning of current flow in a circuit. In contrast, a fixed resistor has a constant resistance value and does not change. While stepped resistors can be used for applications requiring variable resistance, fixed resistors are typically used in applications where a specific resistance is needed. The ability to adjust resistance in stepped resistors offers greater flexibility in circuit design.
