Create a Circuit for an NE555 in Astable Operation Mode with a frequency of 100Hz and a duty cycle of 75%. 

Do this in the following steps and record measurements with a multimeter in the simulation as you go along: 

Select R2, R1 and C according to your calculations from the previous part. Use 1µF 

Place R2, R1 and C onto a breadboard and connect them as in the circuit diagram above to a voltage source (use a 9V Battery). • The voltage between the Ground and the connection between R1 and R2 is   Volts 

The voltage between the Ground and the connection between R2 and C is   Volts? • Now connect the NE555 as well as Caux 

Observe the Voltage between Ground and the OUT Pin of the NE555 using an oscilloscope. The Waveform is a 

Now connect 390R and measure the current through it using an current meter. The current is Milliampere ?
