OCR Applied Science: 6.3 Electrical Properties
This PowerPoint presentation with worked examples and student activities covers:
Topic 6.3 of Module 1: Science Fundamentals of the OCR Applied Science Spec.
Current as flow of charge in a conductor.
Use the equation: I = ΔQ ÷ Δt
Ohm’s law illustrates the relationship of V ∝ I
Use the equation: potential difference (V) = current (A) × resistance
Use the equations for adding resistors in series and parallel
Compare electromotive force and potential difference
Use the equation: charge © = current (A) × time (s)
Use and recognise the equation for mean drift velocity
Use the equation: energy transferred (work done) (J) = charge © × potential difference (V)
Use the equation: energy transferred (J, kWh) = power (W, kW) × time (s, h)
Use the equation: power (W) = energy (J) ÷ time (s)
