• V=IR
• V = m dot * Ve + (pe - p0) * Ae

If resistance increases, what does current do? 

• current stays the same
• current increases
• current decreases
• there will be no current

Total resistance in a series circuit

• R_{t =} R₁ + R₂ + R₃ ...
• 1/R_{t =} 1/R₁ + 1/R_{2 ...}
• R_t = R₁ X R₂ / R₁ + R_{2 ...}
• R_t = R_N / R_V
