The temperature dependence of resistance is also quantified by the relation R2=R1[ 1+(T2T1) ] where R1 and R2 are the resistances at temperatures T1 and T2, respectively, and is known as the temperature coefficient of resistance. If a copper wire has a resistance of 55 at 20C, find the maximum permissible operating temperature of the wire if its resistance is to increase by at most 20. Take the temperature coefficient at 20C to be =0.00382.
The diode current in a p-n junction is modeled exponentially (given below.)

3)We can bias a diode forward or reverse. Soon: a) Directly polarizing means connecting the positive of the supply to the anode of the diode and the negative of the supply to the cathode of the diode.b) When we supply a diode with alternating voltage, the diode will be forward biased when the supply is in the positive quadrant, therefore, allowing the voltage to pass minus the voltage drop across the potential barrier.c) When the diode is forward biased, it conducts an extremely small electrical voltage (leakage current). By increasing this reverse voltage applied to the diode, at a given moment, the breakdown voltage is reached.d) When the reverse voltage applied to the diode reaches the breakdown voltage, the diode stops working momentarily, as a preventive measure.e) When the diode is reverse biased, it conducts an extremely small electrical voltage (leakage current). By increasing this reverse voltage applied to the diode, at a given moment, the breakdown voltage is reached.f) None…
