What is electricity? Electricity is a form of energy that consists of charged particles like protons and electrons. Electricity is important because so many things in our lives require electricity. Our phones, televisions, stoves, refrigerators, even our watches and cars use electricity. If we didn't have electricity, we wouldn't have the convenience that we have today. We wouldn't be able to do things like watch the olympics.
Electric current is the flow of electricity through a conductor. A good example of this is the wires in our homes. They carry an electric current through them. When a current goes through a resistor, it experiences some resistance. This means that in order for the electricity to flow, it needs more voltage than usual. Resistors just require more voltage for electric current to flow.
