Final answer:
In the equation E=VIT, 'I' signifies the current, which can be found by dividing the energy (E) by the product of voltage (V) and time (T), assuming T is a factor in the situation.
Step-by-step explanation:
In the equation E=VIT, I represents the current in the circuit. To solve for I (current), you need to have the values for E (energy) and V (voltage or Hall potential) as part of the equation. The Hall potential can be measured using a voltmeter. The context suggests that this equation may be a manipulation or derivation of Ohm's Law which relates voltage (V), current (I), and resistance (R), expressed in the equation V = IR. Essentially, you can rearrange the equation to solve for I (current) by dividing E (energy) by the product of V (voltage) and T (time) if T is accounted for in the scenario, although T is not part of the classic Ohm's Law.
