Factors Affecting The Size of Current Flowing Around a Circuit To investigate this we first setup an experiment, a circuit diagram of this experiment is below. For this experiment I predict that the current size will decrease as resistance increases, when voltage stays the same value. Also, as voltage increases, so will the current. I predict this due to knowledge that the battery voltage provides energy to move around a circuit, therefore if the voltage is doubled, then the current will be doubled. Also, I know that the current value depends on the value of the resistor as the resistor offers resistance or opposition to moving current. Therefore if resistance is doubled, the current should halve. To test this prediction we did an experiment to see how current changed as resistance increased. To get the best results possible, 10 groups did the same experiment and all results were recorded in the table overleaf. Any...
