In series combination, Current(I) remains same among all the resistors, but voltage(V) changes. So:
V(Equivalent) = I(Equivalent) * R(Equivalent)
R(Equivalent) = V(Equivalent)/ I(Equivalent)
R(Equivalent) = IR1+ IR2+...+IRn / I
R(Equivalent) = I(R1+R2+...+Rn)/ I
R(Equivalent) = R1+R2+...+Rn

What is the relationship of voltage to the resistance in a series circuit?
ohms law use kirchoff's voltage law around the loop
Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
How is the resistance of a resister calculated?
ohms law calculation for a series circuit - Total Resistance = Total Voltage divided by Total Current
Does current effect the resistance in an electric series circuit?
The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.
How do you measur ampere?
You use an "amp gauge" to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!
What is the total voltage drop across a set of resistors in series?
Simply add all of the component's resistances together and that will give you circuits total resistance. If you're dealing with a 'series-parallel', or 'parallel' circuit, the equations will change, but in a simple series circuit, the total resistance is just the total of all the component's resistance.
What is the name of a law of resistance?
The name given to the law of resistance is Ohm's Law.
In a series circuit each device that is added to the circuit decreases the?
Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.
In a series circuit each device that is added to circuit decreases the?

What are the limitations of ohms law?
It requires the ability to multiply and divide. It requires the ability to mentally separate voltage from current and to understand resistance and when to add resistance for series circuits and worse identify and calculate parallel loads.
What is meant by law of resistance?
Law of resistance: What you resist persists. based on the same concept as law of attraction
