For resistances in parallel, total effective resistance is [ 1 divided by (1/R1 + 1/R2 + 1/R3 + . . . . . etc.) ]
For two resistors, this expression can be massaged to show that the net effective resistance is
(R1 R2) / (R1 + R2).
(12 x 4) / (12 + 4) = 48/16 = 3 ohms.
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
When an extra globe is added to a circuit, the total resistance depends on how the globes are connected. If they are connected in series, the total resistance increases because the resistances add together. If they are connected in parallel, the total resistance decreases, as the overall resistance is reduced by the additional path for current flow. Therefore, the change in total resistance depends on the configuration of the globes in the circuit.
It does not contain unidirectional outputAnswerA purely resistive circuit is an 'ideal' circuit that contains resistance, but not inductance or capacitance.
A circuit that contains resistance and capacitance is called an RC circuit. This type of circuit can store and release electrical energy, making it useful in various applications such as timing circuits, filters, and signal processing. The behavior of an RC circuit is characterized by its time constant, which is the product of resistance (R) and capacitance (C).
even though a resistance is not connected in a circuit, it would practically have small resistance due to its components.so practically a LC circuit dosent exist..only a RLC circuit exists

To find the net resistance of the circuit connected to the battery in the figure, you need to calculate the total resistance by adding up the individual resistances in the circuit.
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
In principle, it is infinite. I have not connected a parallel circuit in ages.
The net resistance of the circuit connected to the battery in Figure 1 is the total resistance that the current encounters when flowing through the circuit. It is calculated by adding up the individual resistances of all the components in the circuit.

In a series circuit, just add all the individual resistances, to get the total resistance.
When an extra globe is added to a circuit, the total resistance depends on how the globes are connected.

No, the resistance of a resistor remains the same whether it is connected to a power source or tested out of circuit. The resistance value is an intrinsic property of the resistor and does not change based on the external conditions.
A resistance box is a device that contains a set of fixed resistors that can be connected in various combinations to achieve different resistance values. A rheostat is a variable resistor that can be adjusted to change the resistance in a circuit. A resistor is a general term for a component that resists the flow of electrical current in a circuit and comes in fixed resistance values.
You open one of the leads of resistor connected in electronic circuit while measuring its resistance in order to not introduce error cause by other components in the circuit.
