Electricity

Question 1

current

Answer 1

I = Q / T

Question 2

voltage (current)

Answer 2

V = IR

Question 3

voltage (energy)

Answer 3

V = E/Q

Question 4

power loss

Answer 4

P = I²R

Question 5

power (voltage)

Answer 5

P = IV

Question 6

energy transferred (current)

Answer 6

E = IVt

Question 7

energy transferred (power)

Answer 7

E = Pt

Question 8

resistors in series

Answer 8

R total = R 1 + R 2 + R 3 etc

Question 9

resistors in parallel

Answer 9

1 / R total = 1 / (R 1) + 1 / (R 2) + 1 / (R 3) etc

Question 10

wire resistance

Answer 10

R = (r x L) / A

note: A = πr²
