Resistances in series

The total resistance of a circuit of this type will be greater than any individual resistance.

Calculations

Resistances

R_total = R₁ + R₂ + R₃ + R₄

Conductances

1 G_total = 1 G₁ + 1 G₂ + 1 G₃ + 1 G₄

Example

R₁ = 10Ω
R₂ = 20Ω
R₃ = 30Ω
R₄ = 40Ω

R_total = 10 + 20 + 30 + 40 = 100Ω

Voltages & amperes

If we compare this circuit with the next circuit (4 resistances in parallel instead of series), then this circuit has:

• A larger magnetic effect from the generator
• A smaller magnetic constructor

Because there’s more resistance, which essentially means:

• The generator has to do more effort, ie. supply a greater voltage
• Less energy stored in the magnetic field (a smaller magnetic field),
  because energy is used faster by the resistance
