Electricity and Circuits Flashcards
1
Q
What is the equation for charge?
A
Charge (C) = current (A) x time(s)
2
Q
What is the equation for energy transferred?
A
energy transferred(J) = charge moved(C) x potential difference(V)
3
Q
What is the equation for potential difference?
A
potential difference(V) = current(A) x reistance(Ohms)
4
Q
What is the other equation for energy transferred?
A
energy transferred(J) = current(A) x potential difference(V) x time(s)
5
Q
What is the equation for power?
A
power(W) = energy transferred(J) / time taken(s)
6
Q
What is the equation for electrical power?
A
electrical power(W) = current(A) x potential difference(V)
7
Q
What is the other equation for electrical power?
A
electrical power(W) = current(squared)(A squared) x reistance(Ohms)
