Electric Circuits Flashcards
1
Q
Electric current
A
The rate of charge flow past a given point in an electric circuit
2
Q
Ohm’s Law
A
The potential difference across a conductor is directly proportional to the current in that conductor at constant temperature
3
Q
Electromotive Force (emf)
A
The total amount of electric energy supplied by the cell per coulomb of charge
4
Q
Internal Resistance
A
The opposition to the flow of current offered by cells resulting in the generation of heat
5
Q
Cost of electricity
A
Cost of electricity = Power x time x Price
Cost of electricity = kWh x Price per kWh
6
Q
Resistors in parallel
A
Current dividers
7
Q
Resistors in series
A
Voltage dividers
