Year 10 coursework Week beginning Monday 21st & ending Friday 28th How does the length of a wire affect's its resistance? Prediction I predict that by keeping the voltage the same, the amp measurements will have a strong relationship, but by using only one voltage might be the subject of ohm's law not to work. It may also be proven that by raising the length of the piece of wire the relationship between the resistance will be that, the longer the wire the less resistance happening. Equipments used * Amp meter * Volt meter (set at 4 volts) * Power pack (also set at 4 volts) Experiment After setting up the equipment, I set out the circuit provided on the board. I then drew a result table to record my results and began my experiment. I set the voltage on the power pack to 4 and clipped a crocodile clip on one end of...
