Let the equivalent resistance be R and let there be 3 resistors namely R1,R2 and R3, connected in a parallel way.
Now, the relation is:
1/R = 1/R1 + 1/R2 + 1/R3
In principle, it is infinite. I have not connected a parallel circuit in ages.
Resistance is connected in parallel with voltmeter or say, voltmeter is connected in parallel with resistance.
The equivalent resistance of resistors connected in series is simply the sum of their individual resistances. Therefore, the equivalent resistance of three 8.0-W resistors connected in series is 24.0 W.
To calculate the equivalent resistance in a parallel circuit, you use the formula: 1/Req 1/R1 1/R2 1/R3 ... 1/Rn, where Req is the equivalent resistance and R1, R2, R3, etc. are the individual resistances in the circuit.
Rt = 10
When many resistances are connected in series, the equivalent resistance is greater than the greatest single resistance. When many resistances are connected in parallel, the equivalent resistance is less than the smallest single resistance.
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
If three equal resistors are connected in parallel, the equivalent resistance will be one-third of the resistance in series. This lower resistance will result in a higher current flowing through the resistors when connected in parallel compared to when they are in series. Therefore, the power dissipated by the resistors in parallel will be greater than 10W.
The equivalent resistance through the entire surface is equal to the sum of all the individual resistances in parallel. To calculate this, you would add the reciprocals of each resistance and then take the reciprocal of the sum.
The ratio of the equivalent resistance of series combination to the parallel combination of n equal resistors is (n^2 - 1)/n.
To calculate the uncertainty in equivalent resistance, first determine the resistance values and their uncertainties for each resistor in the circuit. Use the appropriate formula for combining resistances (series or parallel) and apply error propagation techniques. For series resistances, uncertainties add linearly, while for parallel resistances, use the formula for relative uncertainties to combine them. Finally, express the total uncertainty in the equivalent resistance based on the calculated result.
