4.3 - Electricity: Electrical Circuits Flashcards
1
Q
What is a Potential Divider Circuit?
A
A circuit that uses two resistors in series to split or divide the voltage of the supply in a chosen ratio so that a chosen voltage can be provided to another device or circuit
2
Q
What is the Terminal P.d?
A
The potential difference recorded across the terminals of a cell
3
Q
What are Lost Volt?
A
The difference between the e.m.f and the terminal p.d. when a charge flows in the cell
4
Q
What is Internal Resistance?
A
The resistance to electric current of the materials inside of a source of emf. When current flow, energy is transferred to these materials, resulting in the terminal p.d. dropping
