How do you find the resistance of a parallel circuit with n identical resistors?
We have n identical resistors, call them R1, R2 etc up to Rn. All have resistance R. Resistance of the whole circuit = 1/(1/R1 + 1/R2 + ... + 1/Rn) = 1/(n*(1/R)) = 1/(n/R) = R/n So it's the resistance of one resistor, divided by the number of resistors.
What is the voltage of a D-cell battery that is wired in parallel?
Any number of fresh D cells wired in parallel will yield a voltage of 1.5 volts.
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.
What are the differences between digital and analog circuits?
Analog circuits operate on a continuous range of voltages. For example, an audio signal may range anywhere from 0V to 1000mV, and an infinite number of places between. Digital circuits operate on only one of two states: "off" or "on", typically represented as 0 and 1. These on and off states are represented by different voltages in different systems. But any given digital signal will have one of only two distinct values. For example, a typical digital signal will dictate that anything below 1.0V is considered "off", and anything above 4.5V is considered "on". Information in digital circuits is represented as either a consecutive stream of these on and off states ("serial") (ex: 10010110) or a set of signals together representing a value ("Parallel") where 8 wires represent 8 bits of a one byte value.

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 75K resistors must be put in parallel to provide a total resistance of 15K?
5000 For Parallel resistors: Rtotal = R / N Rtotal is total resistance R = Value of resistors N = number of resistors 15 = 75000 / N N = 5000
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 multiplex winding?
a wave winding in which the number of parallel circuits is a multiple of two, other than four, whatever the number of poles
What is resistive 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 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 is the total resistance if they have equal resistances in series in each of rows in parallel?
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 ]
How is the total current in a parallel circuit worked out?
You add up the currents in each branch. The current in each branch is just (voltage acrossd the parallel circuit)/(resistance of that branch) . ==================================== If you'd rather do it the more elegant way, then . . . -- Write down the reciprocal of the resistance of each branch. -- Add up the reciprocals. -- Take the reciprocal of the sum. The number you have now is the 'effective' resistance of the parallel circuit ... the single resistance that it looks like electrically. -- The total current through the parallel circuit is (voltage acrossd the parallel circuit)/(effective resistace of the parallel circuit) .
What is a resistor bank?
In simple way resistor bank contains number of resistors in series or parallel combination. They are connected in parallel to decrease the resistance and increase current rating and power dissipation.And they are connected in series to increase resistance and power dissipation.
Will a series win between a series circuit and a parallel circuit?
No,a parallel will win because it has more power and had equal number of energy!AnswerNeither will 'win'. Each has advantages/disadvantages compared with the other -it depends upon their application. Parallel circuits don't necessarily 'have more power' and an 'equal number of energy' (sic).
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.
How parallel resistors work?
Resistors in parallel work just like highway lanes in parallel. -- The more lanes there are, the more traffic they can carry. -- Any number of lanes in parallel are always wider than the widest single lane, and can carry more traffic than the widest single lane can. "wide lane" = low resistance "narrow lane" = "high resistance" "traffic" = "electric current"
