Electricity Flashcards
1
Q
What is the charge equation (includes potential difference)?
A
Potential difference,V (V) = Work,W (J) / Charge,Q (C)
2
Q
What is the charge equation (includes time)?
A
Charge,Q (C) = Current,I (A) x time,t (s)
3
Q
What is potential difference across a bulb?
A
The amount of energy transferred to the bulb by each coulomb of charge
4
Q
What is Ohm’s law?
A
The current flowing through a resistor as a constant temperature is directly proportional to the potential difference across it
