The Relationship between Resistance, Current, and Electricity

Resistance (in a circuit) is any resistance or opposition against the current flow. The electrical resistance of a conductor is a measure of how difficult it is to push the charges along. To find the voltage, the equation V=IR is used. This equation is called Ohm's Law. Current flow is the number of charges passing through a certain point per second or  the rate at which charge flows past a point on a circuit. The equation used for currents is I=Q/t. Yes, the symbol representing currents in I. The metric unit for current is an ampere or what you might know as an Amp.  A current of 1 ampere means that there is 1 coulomb of charge passing through a cross section of a wire every 1 second. Apparently there are two types of currents; direct current and alternating current. In a direct current, the electric charge flows in a constant or in one direction. Examples of direct current tools are laptop charges, phone charges, battery charges, etc. So, they are mainly appliances that are plugged into the wall and got to another device. The electric charge only travels one way; from the wall to the appliance. In an alternating current, The current flows in one direction for a period of time and then switches direction, going the opposite way, but it does it continuously. Power outlets and power plants are examples of alternating currents. Power outlets can charge more than one appliance, and power plants can send electricity to more than one area.
