4.3 Flashcards
1
Q
Kirchhoffs second law
A
In any closed loop the sum of the emf is equal to the sum of the products of the current and resistance
2
Q
Potential dividers
A
Varying the ratio of a pair of resistors changes the output voltage ions circuit
3
Q
Terminal potential difference
A
Pd measured around the terminals of the battery. The difference between this and the emf is the lost volts
4
Q
Graphical method for finding emf and internal resistance
A
-r= gradient Emf= y intercept
