Electrical Charge and Current

Question 1

Charge

Answer 1

Charge (measured in Coulombs) = current (measured in Amperes) x time

Question 2

Energy Transferred

Answer 2

Energy Transferred = charge moved x potential difference (V)

Question 3

Potential Difference

Answer 3

Energy Transferred (J) / charge moved (C).

Question 4

Resistance

Answer 4

Potential Difference = current (A) x resistance (ohms)

Question 5

Power

Answer 5

Current x Potential Difference

Or

Current (squared) x Resistance
