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.
Yes. Rt=R1+R2
Yes. That's what it does.
The number of resistors and their value. The wire and the junction points have resistance also.
This project will require a parallel circuit, not a series circuit.
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
Too high a resistance is always not a good thing in a circuit. That's what "too high" means.
resistance
Resistances are additive in a 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.
False
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
Yes.
If you add a second resistor, the resistance of series circuit will increase.
The resistance of a series circuit is simply the sum of the individual resistors.
Resistance isn't lost. The largest voltage drop will occur across the largest resistance in a series circuit.
It does not contain unidirectional outputAnswerA purely resistive circuit is an 'ideal' circuit that contains resistance, but not inductance or capacitance.
Voltage is an electrical force or pressure that causes current to flow in a circuit. It is an additive in a series circuit.
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.
A: practically any series resistance will do that
