voltage | The energy carried by the current. It is measured by its difference between two points in a circuit. |
battery | Two or more connected electrical cells, which work together to produce electrical energy. |
current | The flow of electrons in a circuit. |
circuit | A conducting pathway through which current can flow. |
parallel circuit | A type of circuit with components in different branches. There are different paths for electrons to flow through. |
voltmeter | A device used to measure the voltage used or supplied. |
series circuit | A type of circuit in which components are arranged one after another. The electrons all flow through the same path. |
static electricity | A build-up of electrical charges. This happens when certain materials rub against each other and some electrons are transferred from one material to the other. |
conductor | A substance which allows electrons to flow through it. Most are metals. |
ammeter | A device used to measure the current in a circuit. |
insulator | A substance which does not allow electrons to flow through it. |
