No. The reciprocal is additive. The formula for the equivalent resistance, in parallel, is 1/R = 1/R1 + 1/R2 + 1/R3... where R is the total equivalent resistance, and R1, etc. are the individual resistances in parallel. Note that the equilalent resistance will be less than any of the individual resistances.

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.
How do you use series circuit in a sentence?
This project will require a parallel circuit, not a series circuit.
When a resistor is connected to a 25.0 V power supply the current through the resistor is 12.5 A.Calculate the resistance of a second resistor connected in series that reduces the current to 5.00 A.?
R2 = 3 ohms Explanation: For a circuit you can use ohms law where: V=I*R Where V is the voltage difference throughout the surface, I is the current, and R is the total resistance of the circuit. In your case you want to find the resistance so you have to change the formula to: R=V/I R of first circuit = 25volts/12.5amps = 2 ohms R of second circuit= 25 volts / 5 amps = 5 ohms The resistors here are connected in series which means that the resistance of the two can be added together. This gives you: Rtot= R1+R2 we found R of the first resistor by calculating the resistance in the first circuit. We also found Rtot which is the resistance in the second circuit, when you connect the two resistors together in series. Rtot=2 ohms+R2 5ohm=2ohms+R2 R2 = 3 ohms If the resistors where connected in parallel you cannot simply add the resistance. In that case: (1/Rtot)=(1/R1)+(1/R2) Hope that helps
When is too high a resistance not a good thing in a circuit?
Too high a resistance is always not a good thing in a circuit. That's what "too high" means.
What is the ability to regulate the amount of charge flowing in a circuit is?
resistance
How are resistance combined in a series circuit?
Resistances are additive in a series circuit.
Current is additive in a series circuit?
False
What are the rules in series circuit?
Kirchoff's Current Law: The current at every point in a series circuit is the same. This can also be expressed as the sum of the currents entering a node is zero. Kirchoff's Voltage Law: The sum of the voltage drops across all elements in a series circuit add up to zero.
Voltage drops is additive in a series circuit?
Yes.
How is the total resistance in a series circuit is determined?
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
Where is the most resistance lost in a series circuit?
Resistance isn't lost. The largest voltage drop will occur across the largest resistance in a series circuit.
If two light-bulbs are connected in a series circuit and one of the light-bulb's current flowing is 0.5 A what is the current flowing in the other light-bulb?
Current in a series circuit is the same throughout the circuit. Voltages are additive. Voltage in a parallel circuit is the same throughout the circuit. Currents are additive.
What is a resistance circuit?
It does not contain unidirectional outputAnswerA purely resistive circuit is an 'ideal' circuit that contains resistance, but not inductance or capacitance.
Is Voltage the same all parts of a series circuit?
Voltage is an electrical force or pressure that causes current to flow in a circuit. It is an additive in a series circuit.
Is resistance in a series circuit equal to the largest resistor in the series?
No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!
