Equations

Question 1

1) P =

symbol, word, units

Answer 1

P = IV
power = current * p.d
W = A * V

Question 2

2) V =

symbol, word, units

Answer 2

V = IR
p.d = current * resistance
V = A * Ω

Question 3

3) P =

symbol, word, units

Answer 3

P = E / t
power = Energy transferred / time
W = J / s

Question 4

4) P =

symbol, word, units

Answer 4

P = I²R
power = (current)²  * resistance
W = (A)² * Ω

Question 5

5) I =

symbol, word, units

Answer 5

I = Q / T
current = charge flow / time
A = C / s
(C = coulombs)

Question 6

6) E =

symbol, word, units

Answer 6

E = QV
energy = charge * p.d
J = C * V
