The ratio between voltage and current is known as resistance. For most metallic conductors, the relationship between voltage and current is linear.

The purpose of impedance is to generalize the idea of resistance to create a component. To capture the behavior of resistors, capacitors, and inductors, for steadystate sinusoidal signals. This generalization is motivated by the fact that as long as the circuit is linear, its behavior can be analyzed using KVL and KCL.

The result now is a two-part speed-torque curve which features constant torque from zero speed until it intersects the motor’s natural load line, called the corner speed, beyond which the motor is in the constant power region.

This is a set of multiple electronic circuits on a small semiconductor device (normally silicon). With the advancement of technology, these IC’s prove to be extremely beneficial. They are present in any electronic device you can name. From computers, mobiles to other digital appliances you have multiple IC’s present in them. Their main components are a combination of Diodes, transistors and microprocessors. The microprocessors provide memory to the device. With the help of the microprocessor the electronic devices can perform logical or protocol applications.

The real part and imaginary part of impedance are interpreted as a resistive part that dissipates energy and a reactive part that stores energy. Resistors can only dissipate energy and therefore their impedances have only a real part. Capacitors and inductors can only store energy and therefore their impedances have only an imaginary part. When resistors, capacitors, and inductors are combined, the overall impedance may have both real and imaginary parts. It is important to note that the definition of impedance preserves the definition of resistance.

In series regulation the control element is placed between the unregulated voltage source and the load and the current through the element is controlled so that the voltage across the load is held constant. A feedback control system is used where the difference between the output voltage and a reference voltage is applied to a high gain amplifier that drives the current control element such as to maintain the setpoint output voltage. The majority of voltage regulators are of the series type.

In this sort of a connection all the components would receive the same voltage, while the current would be divided amongst the components.
