Association of resistors and power sources

Association of resistors
00:00:03
Circuits can have various electrical components,
00:00:06
but when we are learning the basics we generally only start with cells and resistors.
00:00:09
The way that we put these resistors together is called the association of resistors.
00:00:14
This gives us three types of basic circuits.
00:00:20
Series Cricket
00:00:23
Parallel Circuit
00:00:25
Series Parallel Combination Circuit
00:00:27
To perform the electrical calculations of a circuit with several resistors,
00:00:30
we calculate the value of a single resistor,
00:00:34
equivalent to the association of the resistors in the circuit.
00:00:37
The circuit formed with the equivalent resistances is called an equivalent circuit.
00:00:41
We can obtain three things from this circuit.
00:00:46
The currents flowing through the circuit.
00:00:49
The potential drops across the components.
00:00:51
The dissipated power and the delivered power.
00:00:54
Series Circuits
00:00:57
The equivalent resistance is equal to the sum of all resistances in the circuit.
00:00:59
The current flowing through all of the resistors in the circuit is the same
00:01:04
and is equal to the current of the equivalent circuit.
00:01:08
The total voltage delivered by the power source
00:01:11
is the sum of the potential drops across each of the resistors.
00:01:14
It is a voltage divider.
00:01:18
The power delivered by the power source
00:01:20
is equal to the sum of the powers consumed by each resistor.
00:01:22
Parallel Circuits
00:01:26
The inverse of the equivalent resistance
00:01:28
is equal to the sum of the inverses of all resistances in the circuit.
00:01:30
The current of the equivalent circuit
00:01:35
is equal to the sum of the currents flowing across each of the resistors.
00:01:36
It is a current divider.
00:01:41
The total voltage delivered by the power source
00:01:43
is the same as the potential drops across each of the resistors.
00:01:45
The power delivered by the power source
00:01:50
is equal to the sum of the power consumed by each resistor.
00:01:51
Series-Parallel Combination Circuit
00:01:55
To solve a series-parallel combination circuit,
00:01:58
we need to find out which resistors are in series and which are in parallel.
00:02:01
Then we can apply the equations for each case.
00:02:05
Energy Balance
00:02:08
The ratio of delivered power to power consumed.
00:02:09
The energy balance of the circuit is
00:02:13
Power delivered by the power source equals power consumed by the resistors.
