When two resistors are in series, you add the elements together. When two elements are in parallel you multiply them and divide that by the sum. ie: parallel elements 7 ohms and 8 ohms (8*7)/(8+7).
If there are more than 2 in parallel however, just fill in this:
1/Req=1/R1 + 1/R2 + 1/RN
Req is the final answer of the equivalent resistance.
Rn means you keep adding the reciprocal of the other resistors in parallel.

What is the definition of equivalent resistance?
Equivalent series resistance (ESR) is an effective resistance that is used to describe the resistive parts of the impedance of certain electrical components.
What is the equivalent resistance of three resistor with 3 ohms connected in star?
There is no 'equivalent resistance' for three resistors connected in star.
What is the formula for calculating the equivalent resistance of a series circuit?
Equivalent resistance of a series circuit is the sum of the resistance of all appliances. The formula is R=R1+R2+... where R is equivalent resistance, R1, R2 and so on is the resistance of the individual appliances.
What happens to the resistance of the circuit when you add resistances in parallel?
Adding a resistance in parallel to another resistance will reduce the equivalent resistance. Parallel Equation: R1 = 10Ω R2 = 20Ω Req = R1R2/(R1+R2) = (1/R1+1/R2)-1 Req = 10•20/(10+20) = 6.67Ω
How do you determine the internal resistance of capacitors?
The best way is to check the data sheet and see if ESR (equivalent series resistance) is listed.
What is meant by the equivalent impedance of a parallel ac circuit?
This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.
What is the equivalent resistance through the entire circuit?
The equivalent resistance is the overall effect all of the resistances in a circuit has. Put another way, it is the value a single resistor in a circuit would have to be in order to have the same effect as all of the resistors resistors combined in a given circuit.
How do you calculate thevenis resistance in thevenis ckt?
First,remove all current and voltage sources ie replace voltage source with a short and keep current source open.Now draw the equivalent resistance-only circuit and find the equivalent resistance as viewed from the terminals of the circuit.
How to find Equivalent resistance when you have both parallel and series resistors?
To find equivalent resistance when you have both parallel and series resistors, start simple and expand... Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value. Repeat that process, effectively covering more and more of the circuit, until you arrive at a single resistance that is equivalent to the circuit. For resistors in series: RTOTAL = R1 + R2 For resistors in parallel: RTOTAL = R1R2/(R1+R2)
Three 8.0-W resistors are connected in series What is their equivalent 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.
What is the definition of equivalent resistance?
Equivalent series resistance (ESR) is an effective resistance that is used to describe the resistive parts of the impedance of certain electrical components.
What is the ratio of equivalent resistance of series and parallel combination of n equal resistance to the equivalent resistance on parallel combination?
The ratio of the equivalent resistance of series combination to the parallel combination of n equal resistors is (n^2 - 1)/n.

What The equivalent resistance across a and b is equal to?
r/4If the two resistors are in parallel the find total resistance using this formula (1/R1 + 1/R2) = 1/R total
What is the universal equation for resistance in a parallel circuit?
Total equivalent resistance = reciprocal of (sum of reciprocals of each individual resistance)
How C programming to find equivalent resistance?
for serial: r = r1 + r2; for paralel: r = 1/ (1/r1 + 1/r2);
