Choose the correct experimental circuit arrangement for studying V-I characteristics of a p-n junction diode in forward bias:
In forward bias, the p-side of the diode is connected to the positive terminal of the power supply, and the n-side is connected to the negative terminal. This reduces the potential barrier, allowing current to flow. The correct experimental setup ensures proper voltage and current measurement using an ammeter and a voltmeter. In option (c), the circuit correctly connects the diode in forward bias with appropriate measuring instruments, making it the correct answer.
