Explain how receiver functions in fibre optic communication system.
Receiver:
The optical signal received must be first converted within digital form and in case analog output. Moreover, the analog output has to be amplified to overcome the loss when any throughout its propagation via optical fibre.
A 100V battery is linked across a resistor and causes a current of 5mA to ?ow. Verify the resistance of the resistor. If the voltage is now decreased to 25V, what will be t
