Resistance

Question 1

What is the resistance?

Answer 1

• Potential difference required to drive a current through a component.

Question 2

How do we calculate resistance?

Answer 2

• R= V/I.
  R= Resistance (Ohms).
  V= Potential Difference (V).
  I= Current (A).

Question 3

How do we work out the potential difference?

Answer 3

• V= IR.
  V= Potential Difference (V).
  I= Current (A).
  R= Resistance (ohms).
