Combination Circuits
Name the seven steps to simplify the circuit
1 - Simplify the circuit
2 - Use the Reg
3 - Calculate total current
4 - Calculate total voltage drop
5 - Calculate branch currents
6 - Calculate the voltage in parallel circuits
7 - Make a Summary
Combination Circuits
contain elements of both series and parallel circuits. These elements retain
characteristics
In a series circuit is current the same of different?
Same
In parallel circuits is the voltage the same or different?
Same
,What do variable resistors do?
They can adjust the resistance manually.
What kind of circuit contains elements of both a series circuit and a parallel
circuit
Combination Circuit
How do you identify the series and parallel sections of a combination circuit?
Trace the current path
the representation R1 | | R2 indicates that R1 and R2 are?
Parallel
What should be the first step in analyzing a combination circuit?
Identifying which components are in series and which are in parallel
What happens to the current between the branches of a parallel combination
circuit?
It is split
, Give three examples that switches that can operate several devices at one
time or can operate individual components?
Commercial Building Lighting System
Electrical Outlets Controlled by a Switch
Ceiling fans with lights
What is a variable resistor?
One that can have its resistance adjusted manually
How many terminals does a variable resistor have?
Two or three. But usually three.
Describe the terminals on a variable resistor
The two outside terminals act like a fixed resistor, the resistance between the
two does not change. The center terminal is attached to a slider and is
controlled by a knob.
Two terminal variable resistor
Three terminal variable resistor
