The current flowing through a component depends on: Potential difference is also known as voltage and is measured in volts (V). However, in parallel circuits, the current flow is split between the components that are placed in parallel with each other. Potential dividers are circuits that produce an output voltage as a fraction of its input voltage This is done by using two resistors in series to split or divide the voltage of the supply in a chosen ratio Potential dividers have two main purposes: To provide a variable potential difference To enable a specific potential difference to be chosen Circuit diagrams show which circuits they need and how to connect the voltmeters. Isn't that pretty simple! undefined Since the resistors are connected in series, the total resistance in the circuit will be equal to the sum of the individual resistances. One volt is the potential difference when one coulomb of charge transfers one joule of energy. In a series circuit, if one lamp is removed or broken the other goes out, All three ammeters read 0.5 A in this series circuit, The current in this series circuit increases as more cells are added, The current flowing through each lamp is less when there are more lamps, but it is still the same everywhere in this series circuit. When a charge moves through a potential difference, work is done by the power supply and energy is transferred from it to the component and/or its surroundings. The potential difference (voltage) of the supply is shared between components in a series circuit. Potential Differences in a Series Circuit A cell is connected to two light bulbs in series.
