How do you connect several resistances if you want to decrease in total resistance without reducing the number of resistors?
The resistors should be connected in parallel .
What happens to carbon resistors in parallel?
The resistance R of two or more resistances in parallel is given by: R = 1/(the sum of the reciprocals of the individual resistances). I.e. if each resistor be designated as r(number), then 1/R = 1/r1 + 1/r2 + ... + 1/rn The material from which the components are made is not important in the formula, but may be significant to specific circuit design criteria.
What is Resistance of 20 ohms and 10 ohms?
Well, the total circuit resistance depends on the type of connection. If the two resistances (or any number of resistances) are connected in series, IE. one resistance end is connected to one end of another resistance, the the circuit total resistance is the sum of the two resistances. say two resistances r1 and r2 are connected in series the total resistance is r1+r2 (in this case its 30 ohms). If the resistances are connected in parallel IE. both the ends of a resistance are connected to both ends of another resistance then the total resistance in this case shall be (r1*r2)/(r1+r2) ,( that is 6.67 ohms in given case).
What is a resistance network?
A resistance 'network' consists of a number of resistors connected together in series, or in parallel, or in series-parallel, or as a complex circuit. A 'complex' circuit is one that is not series, parallel, or series-parallel.

How many number of loads does parallel circuit have?
energy source :)
Does amperage increase as the number of bulbs in a parallel circuit increase?
Yes.
What is the difference between Serial and Parallel Adder?
Some key differences between a Serial and Parallel Adder are that a Serial Adder is slower, a Parallel adder is a combinational circuit and the time required for addition depends on the number of bits in a Serial, but not a Parallel. A Serial Adder is a sequential circuit while a Parallel is a combinational circuit.
How is the current affected by the number of bulbs?
As the number of bulbs in a series circuit increases, the current decreases. As the number of bulbs in a parallel circuit increases, the current increases.
How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
What is it true that the combined resistance of a parallel branch circuit equals the value of one branch resistance divided by the number of branches?
Only if the resistances of all the branches are the same. RParallel = 1 / SummationI=1toN (1 / RI) This simplifies to RI / N only if all RI's have the same value.
Which is the total resistance of a circuit that contains twenty 100 ohms resistors connected in parallel?
When resistors of the same value are wired in parallel, the total equivalent resistance (ie the value of one resistor that acts identically to the group of parallel resistors) is equal to the value of the resistors divided by the number of resistors. For example, two 10 ohm resistors in parallel give an equivalent resistance of 10/2=5Ohms. Three 60 ohm resistors in parallel give a total equivalent resistance of 60/3 = 20Ohms. In your case, four 200 Ohm resistors in parallel give 200/4 = 50 Ohms total.
