Q
How is resistance in parallel calculated?
A
Rt = 1 / R₁ + 1/ R₂ + 1 / R₃…
2
Q
What is a coulomb defined as?
A
The amount of charge passing in 1 second if the current was 1 amp
3
Q
What is volt defined as?
A
The amount of energy (in joules) you convert as you move 1 coulomb of charge through a component
4
Q
What are the equations involving internal resistance?
A
ε = I(R + r)
Where ε is e.m.f (electromotive force) measured in volts (E/Q)
