20- In a highly sophisticated electronic device, a semiconductor component exhibits a voltage-current relationship characterized by a nonlinear function. When a voltage of 8 volts is applied across the component, the resulting current is found to be 0.5 amperes. However, when the voltage is increased to 12 volts, the current rises to 1.2 amperes. What is the approximate resistance of this semiconductor component? A) 4 ohms B) 8 ohms C) 10 ohms D) 12 ohms
