3. Series and parallel circuits serve different purposes in households 1. Identify the difference between series and parallel circuits Series is when the components line up after one another, thus there is only 1 path. In parallel there are multiple paths.
Advantages of using parallel circuitry over series circuitry in household wiring include: * You can have some devices on and others off at the same time. * If one device fails the others still work.
* All devices receive the highest possible voltage.
2. Compare parallel and series circuits in terms of voltage across components and current through them In a series circuit voltage is divided evenly throughout the components, with current being the same max current throughout all the components. In a parallel circuit it is opposite, voltage is the same max voltage throughout the components, with current being divided evenly throughout the components.
In the series circuit each light will be half the brightness than if there was only one. However in the parallel circuit the lights have the same brightness no matter how many are added. 3. Identify uses of ammeters and voltmeters
Ammeters are used to measure current. Voltmeters are used to measure voltage. To measure the voltage of a component the voltmeter is placed in parallel with the component. To measure the current passing through a component, the ammeter is placed in series with the component. When an ammeters work best if they have a low resistance. And voltmeters work best if they have a high resistance. 4. Explain why ammeters and voltmeters are connected differently in a circuit Voltage is sometimes called potential difference. So it is measuring the difference between two points, so is must be placed in parallel so that it can measure the difference between before and after that component. Current is a measure of the rate at which charge flows, and therefore must be connected in series. Ammeters have a low resistance. In...
