SCIENCE: INVESTIGATION INTO RESISTANCE Electricity in general Resistance is anything in a circuit which slows down the flow of a current. It can be caused by collisions of the electrons into the material's atoms. The current is the flow of electrons in a wire, and it is literally pushed around the circuit with the help of the force of Voltage (which is generally the pressure difference in a circuit). The resistance opposes the amount of voltage and stops the currents from flowing properly. The amount of current flowing through a circuit is directly proportional to the amount of Voltage or resistance is in the circuit; the current will flow faster with high Voltage and low Resistance as opposed to low Voltage and high Resistance, which would make the current flow slower. The electrons in metals carry the current, and each metal has a "sea of electrons" which can move around easily,...
