Presentation Transcript

### Test on Thursday

An outline…

Topics Covered
• Relays
• Transformers
• Diodes
• Ohm’s Law
• Power
What to expect
• Several multiple choice; based on theory, information from notes, etc.
• Some math
• Eg, calculating power, finding current, voltage, resistance
• Draw some schematics
• Label some diagrams
Formulae
• Ohm’s Law: I = E/R
• Power: I x E = P
• Transformer Formulae
• Ep/Es = Np/Ns
• Is/Ip = Np/Ns
• Ip/Is = Vs/Vp
