a) Put 2 of the resistors in series to make a 200 ohm resistor. Then put the 100, 100, and 200 ohm resistors in parallel for 40 ohms. b) Put 2 resistors in parallel for 50 ohms. Put the 50, 100, and 100 ohm resistors in series for 250 ohms. c) Put 2 resistors in parallel for 50 ohms. Repeat with other 2 resistors. Put the two 50 ohm resistors in series for 100 ohms. This configuration can withstand 4 times the wattage 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.
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.
NOT Possible. In a parallel combination the power tollerence has to increase, thus for every additional resistor in parallel the effective power capacity of the resister would be n(12) Watts where n is the number of resistors connected. ie. if n=3 the power of the combination would rise to 12 x 3 = 36W. Also it is not possible to compute the effective resistance of the combination unless the resitance value of the resitors utilised is known. The question is therefore invalid.
A circuit that uses resistors to produce a voltage lower than the source voltage is called a voltage divider. It typically consists of two or more resistors connected in series, with the output voltage taken from the junction between them. The output voltage can be calculated using the formula ( V_{out} = V_{in} \times \frac{R_2}{R_1 + R_2} ), where ( R_1 ) and ( R_2 ) are the resistances of the two resistors. Voltage dividers are commonly used in electronic circuits for signal conditioning and level shifting.
High skin resistance can produce severe skin burns but prevent the current from entering the body

You can achieve a 30 ohm equivalent resistance by connecting the resistors in a combination of series and parallel. Connect two resistors in series to get 40 ohms, then connect the third resistor in parallel with this combination to achieve a total resistance of 30 ohms.
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.
Linear resistors
To raise the temperature difference without changing the current, you can increase the resistance in the circuit. This can be done by adding additional resistors in series, using a material with higher resistance, or by adjusting the configuration of the circuit to increase the overall resistance. By increasing the resistance, the same current will produce a greater voltage drop across the resistors, resulting in a higher temperature difference.
Chemical elements are combined to produce chemical compounds.

To determine how many resistors need to be made to deliver 5,000 resistors, we must consider production losses, defects, or any other factors that affect the final count. For example, if they expect a 10% defect rate, they would need to produce 5,556 resistors (5,000 divided by 0.9). Therefore, the exact number of resistors to be made depends on the anticipated yield or defect rate in the production process.
A Resistor Is Used To Limit The Current In A CircuitFurther AnswerA resistor is sometimes used to modify the natural resistance of a circuit -e.g. by adding a resistor in series, you can increase the natural resistance; by adding a resistor in parallel, you can decrease the natural resistance. Two or more resistors can be used to create a voltage divider -a method of obtaining a voltage lower than the supply voltage in a d.c. circuit.Use of resistor is to produce a particular amount of resistance to the flow of current

Alloys can add heat resistance to a metal
The complete explanation probably involves quantum mechanics, but for an intuitive explanation, simply imagine that electrons move through a metal (for example), and that now and then, some of them collide with atoms, wasting energy from the electric current - and heating up the metal (by making the atoms move faster).
