Question

A V-I converter uses a \(500\,\Omega\) resistor. For an input voltage of \(2\,\text{V}\), the output current is

• A. \(1\,\text{mA}\)
• B. \(2\,\text{mA}\)
• C. \(4\,\text{mA}\)
• D. \(8\,\text{mA}\)

Hint:

For a voltage-to-current converter, \[ \boxed{ I=\frac{V}{R} } \] where \(V\) is the input voltage and \(R\) is the sensing resistor.

Answer 1

The Correct Option is C

Step 1: Use Ohm's law. For a V-I converter, \[ I=\frac{V}{R}. \] Given, \[ V=2\,\text{V}, \qquad R=500\,\Omega. \]

Step 2: Calculate the output current. \[ I = \frac{2}{500} = 0.004\,\text{A} = 4\,\text{mA}. \] Hence, \[ \boxed{4\,\text{mA}} \] Therefore, \[ \boxed{(C)} \] is the correct answer.
