Explain the DC breakdown voltage vs. electrode distance curve
(Paschen’s law) and how it is relevant to dry etching. How is
miniaturization of an electrode set equivalent to creating a local
vacuum?
Based on resistance measurements, what is the expected turns
ratio Np/Ns?
Based on measurements of Vp/Vs, what do you expect for turns
ratio Np/Ns?
Explain the reason for the discrepancy.
If a transformer is ideal, what is the ratio for Is/Ip? Why are
the experimental and theoretical values different?
Ohm Law and Resistivity
1. According to Ohm's Law, for a constant R resistance Does the current in a circuit increase or decrease if we increase the voltage? Explain your answer based on the corresponding formula.
2. According to Ohm's Law, for a constant voltage, does the value of the current increase or decrease if we decrease the resistance with a rheostat connected in series in the circuit? Explain with your words based on the corresponding formula.
