Ensure that the current is still 0.4 A and repeat current and voltage reading for lengths of 40 cm, 50 cm, 60 cm, 80 cm and 100 cm Calculate the resistance for each length, remembering to switch ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. Electrical circuits can be connected in parallel or in series ...
