Flashcards for Thermal, Waves, Electric, and Nuclear Physics

Energy

mass × specific heat capacity × temperature change

Thermal Capacity

mass × specific heat capacity

Energy Transferred

mass × specific latent heat

Expansion

linear expansivity × original length x temperature rise

Wave Speed

frequency x wavelength

Frequency

1 / Period

Refractive Index (Snell's Law)

sine of the angle of incidence / sine of the angle of refraction

Refractive Index (Speed of Light)

speed of light in vacuum / speed of light in material

Refractive Index (Critical Angle)

1 / sine of critical angle

Current

charge / time

Voltage

energy transferred / charge

Power (Resistance)

current × resistance

Energy Transferred (Electricity)

current × voltage × time

Energy Transferred (Power)

power × time

Resistors in Series

Total Resistance = sum of individual resistors

Resistors in Parallel

1 / total resistance = sum of 1 / individual resistors

Resistance

resistivity × length / area

Transformers (Voltage)

voltage in secondary coil / voltage in primary coil = turns on secondary coil / turns on primary coil

Transformers (Current)

voltage in primary coil / voltage in secondary coil = current in secondary coil / current in primary coil

Energy

mass defect x speed of light
