## Can we convert voltage to current?

As we know, if we apply a voltage VIN across a resistor R, a proportional current IOUT = VIN/R begins flowing through the circuit. We may say that this is a voltage-causes-current formulation of Ohm’s law: I = V/R. A bare resistor can convert the voltage into current.

## What are the application of voltage to current converter?

Application of Voltage to Current Converter

• Zener diode tester.
• Low AC and DC Voltmeters.
• Testing LED.
• Testing Diodes.

Which amplifier is also called as voltage to current converter?

Explanation: Voltage to current converter is also called as current series negative feedback amplifier because the feedback voltage across internal resistor applied to the inverting terminal depends on the output current and is in series with the input difference voltage.

What is the expression of output voltage of voltage converter?

So, the voltage at the inverting input terminal of the op-amp will be zero volts. Thus, the output voltage, V0 of current to voltage converter is the (negative) product of the feedback resistance, Rf and the input current, It.

### What are the applications of IV converter?

Applications of I – V Converter: Sensing current through Photodetector. Such as photocell, photodiodes and photovoltaic cells. Photoconductive devices produce a current that is proportional to an incident energy or light (i.e) It can be used to detect the light.

### Why do we need voltage to current converter?

A current to voltage converter will produce a voltage proportional to the given current. This circuit is required if your measuring instrument is capable only of measuring voltages and you need to measure the current output.

What is the other name of I V converter?

Voltage to Current Converter with floating loads (V/I) : This circuit is also called as a current – series negative feedback amplifier. Because the feedback voltage across R1 (applied Non-inverting terminal) depends on the output current i0 and is in series with the input difference voltage Vid.

How do you convert current output to voltage?

How to Convert Current to Voltage using Resistor ?

1. R = 10V/0.020A = 500 Ohms.
2. R = 5V/0.020A = 250 Ohms.
3. Note:-

#### How does NPN transistor work?

The NPN transistor is designed to pass electrons from the emitter to the collector (so conventional current flows from collector to emitter). The emitter “emits” electrons into the base, which controls the number of electrons the emitter emits.

#### How does a transistor operate?

The transistor works because of something called a semiconducting material. A current flowing from the base to the emitter “opens” the flow of current from the collector to the emitter.

What is a transistor amplifier circuit?

Transistor as an Amplifier Amplifier circuit can be defined as, a circuit which is used to amplify a signal . The input of the amplifier is a voltage otherwise current, where the output will be an amplifier input signal. An amplifier circuit which uses a transistor otherwise transistors is known as a transistor amplifier.

How does a PNP transistor work?

PNP Transistor. A PNP transistor receives positive voltage at the emitter terminal. The positive voltage to the emitter allows current to flow from the emitter to the collector, given that there is negative current to the base (current flowing out of the base to ground).
