An automated external defibrillator (AED) is designed to deliver a rapid, controlled pulse of electrical energy through a patient's chest to restore normal heart rhythm.
During a therapeutic shock, a potential difference of 1600 V is applied across the electrodes.
A total charge of 0.080 C is transferred through the chest tissue in a time interval of 4.0 ms.
Calculate the electrical resistance of the pathway between the electrodes.
Practise AQA GCSE Physics Current, potential difference and resistance with exam-style questions for Foundation and Higher tier. 82 questions covering Standard circuit diagram symbols, Electrical charge and current, Current, resistance and potential difference, and Resistors, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
