greetings,
in case of signals we always deal with voltage why not current?

actually current can't exist without voltage
Voltage is a measure of the electrical potential difference between two points. In the context of signals, voltage represents the strength or magnitude of the signal. It is a convenient way to measure and manipulate signals as it can be easily converted to other forms such as current or power.
While voltage is the most commonly used quantity to represent signals, other physical quantities such as current, power, or even light can also be used. However, these quantities may require additional equipment or may not be as easily manipulated as voltage.
Yes, there are several advantages to using voltage to represent signals. Voltage is a measurable quantity that can be easily manipulated using electronic components, making it ideal for transmitting and processing signals. Additionally, voltage signals are less susceptible to interference and noise compared to other physical quantities.
One limitation of using voltage to represent signals is that it is a relative measure and can vary depending on the reference point. This means that voltage signals must be referenced to a common ground in order to be accurately measured and processed. Additionally, voltage signals may also be affected by factors such as resistance, capacitance, and inductance in a circuit, which can distort the signal.
While voltage is commonly used to represent electrical signals, it may not be suitable for all types of signals. For example, in the case of digital signals, voltage is used to represent binary values of 0 and 1. However, other types of signals such as audio or video signals may require different methods of representation.
