👉 Why is voltage required for an electric current?
In the context of electrical power sources, voltage is the amount of potential energy available (work to be done) per unit charge, to move charges through a conductor.Because voltage is an expression of potential energy, representing the possibility or potential for energy release as the charge moves from one “level” to another, it is always referenced between two points.

👉 Why is voltage required for an electric current equation?
Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current). So, when we talk about these values, we're really describing the movement of charge, and thus, the behavior of electrons.

Input voltage is the voltage required to operate the device. Frequency range describes the range of values of the input frequency that the sensor can operate. Response time is the interval between the application of an input excitation and the appearance of the corresponding output signal.
A current sensor is a device that detects and converts current to an easily measured output voltage, which is proportional to the current through the measured path. There are a wide variety of sensors, and each sensor is suitable for a specific current range and environmental condition. No one sensor is optimum for all applications.
The current sensor is a device that detects and converts current to get an output voltage, which is directly proportional to the current in the designed path. When current is passing through the circuit, a voltage drops across the path where the current is flowing. Also, a magnetic field is generated near the current-carrying conductor.
All energy meters contain both voltage and current sensing elements. Current sensing is a more difficult problem. Current sensor requires wider measurement dynamic range, it also needs to handle a much wider frequency range because of the rich harmonic contents in the current waveform.
A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal could be analog voltage or current or a digital output. The generated signal can be then used to display the measured current in an ammeter, or can be stored for further analysis in a data acquisition system, or can be used for the purpose of control.
In order for a 4-20mA current loop pressure transmitter to function within its designed performance levels a minimum voltage must be maintained across the two electrical connections to the device. Since the electrical configuration is a current series loop circuit any load resistance added to the circuit will consume power resulting in a voltage drop across the component.
If you were thinking about using a circuit with, say, a 160mV voltage source and a series 100 ohm resistor to measure the current, you'd have substantially changing current through the sensor (so you'd get less resolution in degrees at high temperatures for a given resolution or noise floor), and the self-heating would greatly increase at low temperatures rather than appearing as a (relatively) fixed offset temperature.
Whereas measurement of current is an Intrusive task which cannot be detected directly as voltage. ACS712 For measuring current in a circuit, a sensor is required. ACS712 Current Sensor is the sensor that can be used to measure and calculate the amount of current applied to the conductor without affecting the performance of the system.
Excitation Voltage is the voltage level required by a sensor. This is applied at a constant current. The total voltage difference across an IEPE sensor’s terminals is the sum of output bias voltage and the output signal. As an example, here is a specification excerpt for PCB accelerometer model 352C03:
Thermistors and RTDs are resistive sensors that require a current excitation to create a measurable voltage across the device. A constant and precise current source is critical to ensuring an accurate and consistent voltage for measurement.

Does electric field depend on voltage or current?
Again no. The electric field depends on the spatial rate of change (technically called a gradient) of the electric potential. It does NOT depend on the actual value of the potential.
What causes an electric shock current or voltage?
When a voltage is applied to a human body, the amount of current flows through the body depends on the body resistance which varies from people to people. Though, shock is the sensation felt due to the flow of current through the body, voltage is required to cause the flow of current. So, electric shock is the combination of both voltage and current.
What is the definition of electric current voltage?
In particular, we define current at a specific point: the current is the number of coulombs of charge passing by that point per second. In many cases, a stronger electric force (meaning a higher voltage) produces a higher current, because the charges are pulled faster toward ground.
