To summarize all that we have just learned:
There are 2 types of circuits.... Series and Parallel.
- Series Circuits
- Are connected in a straight line, like a chain.
- All current remains the same throughout the circuit.
- There can be many different voltages in a series circuit, as a voltage drop appears across every resistor.
- The total voltage in a series circuit is equal to the sum of all the individual voltage drops within the circuit.
- The total resistance in a series circuit is equal to the sum of all the individual resistances within the circuit.
-
The formula for Resistance in Series is:
-
R
Total
= R
1
+ R
2
+ R
3
+ etc...
-
I
Total
= I

=I

3
etc...
-
E

+ E

+ E

-
Parallel Circuits
- Are connected allowing multiple paths for current flow.
- All voltage remains the same throughout the circuit.
- There can be many different currents in a parallel circuit, as each leg has the same voltage, but can have a different resistance.
- The total current in a parallel circuit is equal to the sum of all the individual currents on each leg of the circuit.
-
The formula for Current in Parallel is:
-
I
RTotal
= I
R1
+ I
R2
+ I
R3
+ etc...
- Resistance is found by reciprocating the sum of the reciprocals of the resistance of the individual branches
-
The formula for Resistance in Parallel is:
-

- Ohm's Law states that there is a relationship which exists between current, resistance, and voltage, such that E = I x R
