Revise Edexcel GCSE Physics 10.2.3 Series and parallel resistance with the question bank and revision guides.
Explain why, if two resistors are in series, the net resistance is increased, whereas with two in parallel the net resistance is decreased. • Calculate the currents, potential differences and resistances in series circuits. • Explain the design and construction of series circuits for testing and measuring. Core Practical: Construct electrical circuits to: a investigate the relationship between potential difference, current and resistance for a resistor and a filament lamp b test series and parallel circuits using resistors and filament lamps.
