## What is a Sinusoidal Wave Signal – Definition and Importance

Updated on 19-Dec-2022 13:43:58
A sinusoidal wave signal is a type of periodic signal that oscillates (moves up and down), periodically. The geometrical waveform of a sinusoidal signal forms an S-shape wave in one complete cycle. A sinusoidal can be a sine functioned signal or cosine functioned signal. Thus, a sinusoidal signal can be defined as, $$\mathrm{y=sin\, x}$$ $$\mathrm{y=cos\, x}$$ Both sine and cosine signals are the types of sinusoidal wave signals. But, the cosine signal is advanced with respect to the sine signal by 90° in time. The sinusoidal wave signal has a smooth wave that oscillates above and below zero and used ... Read More

Updated on 19-Dec-2022 13:42:18
What is a Bleeder Resistor? In electronic circuits, a resistor which is connected in parallel with the output of a high voltage power supply for discharging the filter capacitors of the power supply when the circuit is turned off is referred to as a bleeder resistor. It is also known as a leakage resistor or capacitor discharge resistor or safety discharge resistor. The bleeder resistor is primarily used for safety reasons because it eliminates the possibility of a left over charge that may cause an electric shock. Generally, a bleeder resistor is a standard resistor instead of a specialized ... Read More

In an electric circuit, when two or more electric circuit components are joined together in such a way that there is only one path for the flow of electric current, such connection of circuit components is referred to as series circuits. Therefore, in a series circuit, the current through all the circuit component remains the same, but the voltage across each element is different. In this article, we will discuss about the voltage in series circuits and how to calculate it. What is Voltage in Series Circuits? In a series circuit, the voltage across each element is different and depends ... Read More

A voltage regulator is an electronic circuit which is used to control the variations in the output voltage of a power supply so that it will remain within the suitable limits. Since, in the case of practical circuits, the voltage changes due to several reasons such as change in input voltage, change in temperature of the circuit components, etc. But, ideally, the voltage output of the power supply should be in a certain range that is acceptable for the connected circuit. This is achieved by using a circuit called voltage regulator. In this article, we will discuss the different types ... Read More
