March 28, 2023 By Wat Electrical

This article lists 50 Voltage to Current Converter MCQs for engineering students. All the Voltage To Current Converter Questions & Answers below includes a hint and a link to the relevant topic wherever possible. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of the Voltage To Current Converter.

A voltage-to-current converter is a type of electronic circuit that converts an input voltage signal into an output current signal. This type of circuit is useful in many applications, including signal processing, control systems, and instrumentation. 

The VCCS is a type of voltage-to-current converter that uses an operational amplifier (op-amp) and a feedback resistor to produce an output current that is proportional to the input voltage. 

The transconductance amplifier is a type of voltage-to-current converter which is an amplifier that produces an output current that is proportional to its input voltage. The output current is given by the formula Iout = gm * Vin, where gm is the transconductance gain of the amplifier. 

The trans-impedance amplifier and the conveyor converter are also types of V-I converters. The trans-impedance amplifier circuit converts an input voltage into an output current by using an op-amp and a feedback resistor. The current conveyor system circuit uses a current conveyor to convert an input voltage into an output current.
