By the end you’ll be able to

select and place an ammeter in series and a voltmeter in parallel to measure current and potential difference correctly
draw and interpret standard circuit diagrams using recognised symbols for cells, switches, lamps, resistors, variable resistors, diodes, thermistors, light-dependent resistors, ammeters and voltmeters

0% read

plan and describe investigations of current, potential difference and resistance, identifying independent, dependent and control variables

obtain and process data from electrical practicals, including taking repeat readings, plotting graphs and determining resistance or other quantities from measurements

evaluate electrical practical methods by identifying hazards, sources of error, limitations of apparatus and improvements to increase accuracy or reliability
