Year 10 Physical

I can describe how an LDR or a thermistor can be used in a sensing circuit.

I can calculate p.d. across one of two components in a series circuit with a battery.

I can take readings from I–V graphs and use these to describe the changing resistance of a component.

I can interpret an I–V graph of a diode in order to describe its properties.

I can explain why the resistance of a metal filament changes as the p.d. across it increases.

I can find the resistance of a filament lamp by measuring the current and p.d. for a suitable range of p.d.

I can make calculations using the equation Q = m × L

I can use the particle model to describe the effect of heating to melt a solid or to boil a liquid.

I can measure the specific heat capacity of water and of a metal sample.

I can make calculations using the equation ΔE = mcΔΘ.
