Adding more resistors in parallel always decreases the total effective resistance.
So the total effective resistance of an infinite number of them would be zero ohms.
Nice ! To build a superconducting ring, all you need is an infinite number of resistors.
You don't need the liquid helium, and it superconducts at room temperature !
What else can I help you with?
Why does resistance decrease as the NTC Resitor becomes warmer?
In NTC (Negative Temperature Coefficient) resistors, as the temperature increases, the number of charge carriers also increases. This results in more electron movement, decreasing the resistance. The relationship between temperature and resistance in NTC resistors is inversely proportional.
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"
Choose true or falseIf all the resistors in a parallel sub-circuit have the same value the total current can be found by multiplying the current by the number of resistors?
False. The total current in a parallel sub-circuit where all resistors have the same value cannot be found by multiplying the current by the number of resistors. In a parallel circuit, the total current depends on the individual resistor values and how they affect the overall resistance of the circuit.
What does adding more resistors to a paralles circuit decrease the equivalent resistance of the circuit?
This is a direct consequence of Ohms Law. Since each new resistor connected in parallel will allow more current to flow, the resistance of the circuit must be lower. R = E/I. Since I (current) has increased, and the voltage E is still the same, it follows that R (resistance) must be smaller. That's the way Ohms Law works.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
What is the relations for the equivalent resistance of a number of resistors connected in series?
Resistance in series is simply the sum of the resistors. RSERIES = SummationI=1,N(RI)
What is the rule for finding the total resistance of a number of resistors connected in series?
If the resistors are in series, then the total resistance is simply the sum of the resistances of each resistor.
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 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 .
How many number system exist?
infinit
What is the effect on the total resistance if increase in resistors in series?
That depends ... in a very interesting way ... on whether they are connected in series or in parallel. -- If the resistors are in series, then the total resistance increases when you add another resistor, and it's always greater than the biggest single one. -- If the resistors are in parallel, then the total resistance decreases when you add another resistor, and it's always less than the smallest single one.
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.
Why does resistance decrease as the NTC Resitor becomes warmer?
In NTC (Negative Temperature Coefficient) resistors, as the temperature increases, the number of charge carriers also increases. This results in more electron movement, decreasing the resistance. The relationship between temperature and resistance in NTC resistors is inversely proportional.
Carbon resistors are not available in market of each number of resistance why?
carbon resistors of standard values are manufactured because other values can be obtained by series and parallel combination of standard values. Moreover even standard values do not offer exact Resistance's will have tolerance
How many 176 ohm resistors in parallel are required to carry 5A on a 220V line?
1 resistor has 176ohm resistance (in paralel) ---> given current (I) = 5 A Potential difference (V) = 220 V total resistance = V/I = 220/5 = 44 let the number of resistors be x , 176/x = 44 x = 176/44 = 4 therefore the number of resistors is 4. :)
What factors affect current strength in a series circuit?
The number of resistors and their value. The wire and the junction points have resistance also.
