What is the total resistance of 1 ohm and 100 ohm resistors in parallel?
Less than one ohm
1/（1+1/100）=0.9900990099009900990099……
What is the total resistance of 100 484 ohm resistors in parallel
The total resistance of the parallel circuit is equal to the reciprocal of the reciprocal sum of the partial resistances
R total = 1 / (1 / R1 + 1 / r2 + ·· + 1 / RN)
If each resistance is equal, then
R total = 1 / (1 / R1 + 1 / r2 + ··· + 1 / RN) = R1 / n
In this problem, r = 484 euro / 100 = 4.84 euro
A 1 ohm resistor in parallel with a 100 ohm resistor has an equivalent resistance ()
R = R1 * R2 / (R1 + R2) = 100 * 1 / (1 + 100) = 100 / 101 ohm
What is the total resistance of five 20 ohm resistors in parallel
Formula!
Four ohm! Add five one twenties and divide by one! Add five one twenties and find the reciprocal. The reciprocal is 20 out of 5, which is four ohm!
For example, a 10 ohm resistor, a 20 ohm resistor and a 30 ohm resistor are connected in parallel
Then use 1 / (1 / 10 + 1 / 20 + 1 / 30) to get the equivalent resistance after parallel connection!
