The efficiency of a half wave rectifier is 40%. What happens to the remaining 60% power? Is it wasted?

Draw the circuit diagram of a half wave rectifier using a junction diode.

What happens when 80% of copper combines with 20% of tin?

What happens when 70% of copper react with 30% of zinc?

In a half wave rectifier, a p-n junction diode with internal resistance 20 ohm is used. If the load resistance of 2 kiloohm is used in the circuit, then find the efficiency of this half wave rectifier.

An ac input signal of frequency 60 Hz is rectified by a half wave full wave rectifier. Draw the output waveform and write the output frequency in each case.

What happens when 90% of copper combines with 10% of aluminium?

Explain what happens when 68% of lead combines with 32% of tin?

What happens when 10% of aluminium and 90% of copper combine together?
