Electricity

Question 1

Equation for current

Answer 1

I = Q/T
Current = charge/ time

Question 2

Equations for potential difference

x2

Answer 2

V = W/Q
Potential difference= work done/charge

V= I x R
Potential difference = current / resistance

Question 3

Equations for power

x3

Answer 3

P= E/T
Power = energy / time 

P= I x V
Power = current x potential difference 

P= i2 x R
Current. Resistance

Question 4

Equation for energy

Answer 4

E = V x Q
Energy= potential difference x charge
