Chapter 10 - Electrical Circuits Flashcards
1
Q
State Kirchoff’s second law
A
In any circuit, sum of the EMFs = sum of the P.D.s.
2
Q
Explain Kirchoff’s second law in terms of the conservation of energy
A
Work done by the EMF on the charge carriers = Work done by the charge carriers throughout the circuit.
3
Q
What is meant by ‘lost volts’?
A
The energy wasted per coulomb overcoming internal resistance.
4
Q
What is the terminal potential difference?
A
The potential difference at the terminals of a power source.
5
Q
How do you find total resistance in a parallel circuit?
A
1/R = 1/R1 +1/R2 + …
