A relay can control an electrical circuit by opening and closing its contacts. Connect the circuit below and switch the power supply on or off in order to switch the motor on or off. 6. DESIGNING AN OSCILLATOR \( \mathrm{V}=1000 \mu \mathrm{F}, 12 \mathrm{~V} \mathrm{RELAY}, \mathrm{LED} \) - Build the circuit on breadboard using a capacitance of 1000 uf - Use an oscilloscope to measure the switching frequency over the LED - Replace the 1000 uF with a \( 4700 u F \) capacitor and note the oscillating speed. - Use an oscilloscope to measure the switching frequency over the LED - Observe carefully and explain in your report how this circuit operates. - Also indicate the current direction for each cycle of the oscillation.
