Episode 108: Resistance
From the Institute of Physics, this learning episode provides a quantitative definition for resistance (R = V / I) which reinforces the qualitative notion that more resistance means less current. It looks at Ohm’s law, describing that this is not the same thing as the definition of resistance.
Activities include:
• demonstrating resistance in an electrical circuit
• defining and calculating resistance
• investigating the voltage and current characteristics in a constantan wire
• Ohm's law and ideas of ohmic and non-ohmic behaviour
• student calculations (and answers) with currents given in amps, milli-amps and micro-amps
