Investigation: how the resistance in a circuit varies with the length‚ thickness and type of wire Introduction A current is a flow of negative electrons around a circuit or electrical pathway. This is measured in how many electrons per second or the charge they are carrying go round the circuit (amps or amperes) Voltage or Potential Difference measures how much energy individual electrons have to use up as they go around a circuit. (Volts) Components in a circuit have a Resistance value which

Electricity is a form of energy. Electricity is the flow of electrons. All matter is made up of atoms‚ and an atom has a center‚ called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton‚ and the number of electrons in an atom is usually equal to the number of protons
