- How is a solid-state diode tested? Explain.arrow_forwardThe 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.arrow_forwardWhile constructing a Bridge rectifier, the designer mistakenly has swapped the terminals of D3 as shown in the figure below, where • Diode D3 is damaged so that it is always open circuit regardless of the applied voltage. • vs(t) is a sinusoidal signal with a peak value (Vs = 5 V). • Diodes are modelled using the constant voltage model with VDO = 0.7 V • The ac line voltage has an rms value of 120 V and a frequency (f) = 60 Hz • The resistance RL = 10 kohm. a) Calculate the transformer turns ratio (N1/N2) if vs(t) is obtained from the secondary side of the transformer whose primary side is connected to the ac line voltage (which has a 120 V rms value). b) Plot in the same graph the input signal vs(t) and the output signal vout(t) (show all details including amplitudes, time instances, etc.) c) Calculate the rms values of the output signal vout(t).
