Compléter 1SBO/1SRO Voltage and resistance vocabularyVersion en ligne Complete the text with the information that you studied from unit 2.6.2. par Cristina Hernández Alcaine 1 The amount of current ( in amps ) flowing through a circuit will partly depend on the electromotive force ( EMF ) of the electrical supply . Electromotive force is measured in volts and is generally called . It depends on the " strength " of the electrical supply . The amount of current will also depend on electrical . This value , in ohms , is a measure of how easily current can flow through the conductors and components in a circuit . For example , a lamp creates resistance because the , the metal wire inside it , is very thin . This limits the amount of current that can flow . Resistance also depends on the materials used as . For example , copper has a low resistance and so is a good conductor . Materials with very high resistance , such as plastics , are called eletrical . Only very high voltages cause current to flow through them . Materials that are good insulators are used to insulate conductors . An example is plastic insulation around electric wires . This stops people from touching the conductor and , if it is live ( carrying current ) , from getting a dangerous electric .
