The IWK is a teaching hospital and is affiliated with Dalhousie University. The hospital is also renowned as a research hospital in the areas of children's and women's health. multi-year fundraising campaign ensued, raising $6,000 by 1907; later that year a donation of $10,000 by the late Mr. F.D. Corbett resulted in the beginning of construction of the Halifax Children's Hospital which opened for use in 1909.

The basic condition necessary to produce current flow without a Voltage source is that you must have a closed circuit.
The three basic principles for this tutorial can be explained using electrons, or more specifically, the charge they create: 1  Voltage is the difference in charge between two points. 2  Current is the rate at which charge is flowing. 3  Resistance is a materialâs tendency to resist the flow of charge (current). So, when we talk about these values, weâre really describing the movement of charge, and thus, the behavior of electrons. A circuit is a closed loop that allows charge to move from one place to another. Components in the circuit allow us to control this charge and use it to do work. Georg Ohm was a Bavarian scientist who studied electricity. Ohm starts by describing a unit of resistance that is defined by current and voltage.
