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 else can I help you with?
What happens to resistance when resistors are wired in parallel delta circuit?
What do you mean by a 'parallel delta' circuit -is there such a connection.
Why a circuit will produce a loading effect?
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.
What picture represents two resistors wired in parallel?
It represents that two resistors are connected in parallel.
What happens to the effective resistance of a circuit when additional resistors are added in parallel resistors already present?
When additional resistors are added in parallel to existing resistors in a circuit, the effective resistance decreases. This is because parallel resistors provide multiple pathways for current to flow, which reduces the overall resistance. The total or equivalent resistance ( R_{eq} ) can be calculated using the formula ( \frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \ldots + \frac{1}{R_n} ), indicating that adding more parallel resistors results in a lower ( R_{eq} ).
What happens if 3 resistors connected in parallel and one of the resistors is open circuited?
When one resistor in a parallel circuit is open-circuited, it effectively becomes an infinite resistance and no current flows through it. The total resistance of the parallel circuit increases, but the remaining resistors continue to function normally. The overall current through the circuit will decrease because the total current is now only dependent on the remaining active resistors. The voltage across all parallel resistors remains the same as before the open circuit occurred.
Is the voltage constant in parallel resistors?
In parallel resistors, the voltage across each resistor is the same, but the total voltage across all resistors may vary.
What happens to the voltage values of other resistors when a short occurs in one of them?
If a short occurs in a resistor in series with other resistors, the voltage drops across the other resistors will increase. If a short occurs in a resistor in parallel with other resistors, the voltage drops across the other resistors will decrease, to zero.
What is the advantage of film resistors over carbon resister?
Film resistors have lower noise than carbon resistors.
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 can you determine if resistors are in series or parallel?
Resistors are in series if they are connected end-to-end, creating one path for current to flow. Resistors are in parallel if they are connected side by side, providing multiple paths for current to flow. You can determine if resistors are in series or parallel by examining how they are connected in a circuit.
What is carbon composition?
Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.
How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
