COMEDK 2024 Morning Shift | Semiconductor Devices and Logic Gates Question 18 | Physics

An ideal diode is connected in series with a capacitor. The free ends of the capacitor and the diode are connected across a $$220 \mathrm{~V}$$ ac source. Now the potential difference across the capacitor is :

$$110 \mathrm{~V}$$

$$311 \mathrm{~V}$$

$$2 \sqrt{110} \mathrm{~V}$$

$$\sqrt{220} \mathrm{~V}$$

Though $$\mathrm{Sn}$$ and $$\mathrm{Si}$$ are $$4^{\text {th }}$$ group elements, $$\mathrm{Sn}$$ is a metal while $$\mathrm{Si}$$ is a semiconductor because

$$\mathrm{Sn}$$ has more electrons than $$\mathrm{Si}$$

The energy gap of $$\mathrm{Sn}$$ is zero volt while that of $$\mathrm{Si}$$ is $$0.07 \mathrm{~V}$$

The energy gap of $$\mathrm{Sn}$$ is $$1.1 \mathrm{~eV}$$ volt while that of $$\mathrm{Si}$$ is $$0.07 \mathrm{~V}$$

$$\mathrm{Sn}$$ has more holes than $$\mathrm{Si}$$
