Principal types of electrical circuits:
|
Series circuit
Parallel circuit |
|
|
A circuit in which the current has only one path to travel.
All component parts are end to end. |
Series circuits
|
|
|
The voltage is ____ between the loads in a Series circuit.
|
Divided ( shared )
|
|
|
A circuit in which there are more than one path for the current to flow.
The components are branches of the main circuit. |
Parallel circuits
|
|
|
Type of circuit that:
Each branch receives source voltage. Current flow through each branch can be different. |
Parallel circuits

|
OHMS LAW for Series circuits:
Resistance: |
Resistance: RT=R1+R2+R3
Total resistance is equal to the sum of the separate resistance. |
|
|
OHMS LAW for Series circuits:
Current: |
Current: IT=I1=I2=I3
Current in a series circuit is the same everywhere in the circuit. |
|
|
The amount of potential difference across a resistor.
This is the amount of voltage required to push a specific amount of current across a resistor. |
Voltage drop (IR drop)
|
|
|
Formula for voltage drop:
|
VT=V1+V2+V3
The sum of the voltage drop must add up to the EMF or Voltage of the source. |
|
|
Is the amount of voltage or electrical pressure that is used up or given up as electrons pass through a resistance.(load)
All voltage will be used up in the circuit. |
Voltage drop
|
|
|
When more than one load exist in a circuit, the voltage divides and will be shared among the loads. Depending on the resistance, each load will have a different voltage drop.
|
Voltage drop total
