Connect the above components so that flipping the switch on
and off will turn the DC 5-volt relay on and off. The relay should turn
the light on and off.
- Calculate the peak voltage that 12.6 Vrms will give you.
This will be approximately what you'll get once the capacitor smooths
out the ripple on the pulsating DC coming from the diode bridge.
- Calculate the ohms and watts for the resistor you'll need to put in series with the relay coil (so as to not burn it out).
- After your simulation is working, build the circuit with
real components. Use a small 5-volt relay (with a 165 ohm coil) that
can be plugged directly into the breadboard.
