What are the properties of series circuit ? – TechnologyReport
In a series circuit all elements connected to it have the same current, with symbol I, also called intensity, measured in Amperes. On the contrary, each element has a different voltage unless there are two of the same elements.
For example. You have a 10 Volts battery, connected to 3 resistances: 1 ohm, two ohms, and 2 ohms.
If you sum the resistances, you have a equivalent resistance of 5 ohms and a power source of 10 volts. That produces a current for all the series circuit of 10 V / 5 ohms = 2 Amperes
However, the voltaje needed for each element is not the same in series circuit: from the Ohm’s law: V=I x R so, if each element has a current of 2 amperes going trough, we calculate the voltage in this way:
Vr1=2 Amp x 1 ohm= 2 Volt
Vr2=Vr3= 2 Amp x 2 ohm= 4 Volt
In parallel circuits is the total opposit: current changes, but voltage is the same in each ramification
The circuits called “mixed” are that, a mix between parallel and series circuits that finally can be and need to be reduced to a batt-resistance equivalent circuit to be able to calculate it.
