In a p-n junction diode, the current (i) varies with applied biasing voltage (V) and can be expressed as i=i₀ (e^ q V / kT -1 ) where i ₀=5 10⁻¹² ~A is reverse saturation current, k is Boltzmann constant and q is the charge on the electron At Absolute Temperature T =300 ~K

Options

1. AThe forward current is approximately 59.5 mA for a forward bias of 0.6 volt
2. BThe current increases approximately by 2.75 A if the biasing voltage changes from 0.6 V to 0.7 V
3. CThe dynamic resistance of p-n junction is approximately 435 ~m at the biasing voltage of 0.6 V
4. DThe change in reverse bias current when biasing voltage change from -1 volt to -2 volt happens to be practical
