Circuits

A cell has two ends, labelled + (positive) and – (negative). A cell pushes the electric current from the positive terminal round to the negative one. This is the way that conventional current flows

Two or more cells can be connected end-to-end to make a battery. A typical cell has a voltage of 1.5 volts (we write this as 1.5 V). By connecting cells in series, we can makes batteries with 3 V, 6 V and so on. Each battery is labelled with its voltage. This tells us about the ‘push’ it gives to make the current flow. A 6 V battery gives a bigger push than a 1.5 V cell. Sometimes we call a single cell a ‘battery’, although technically we ought to say ‘cell’.

Answer the following questions:

1) What is a voltage?

2) What is the difference between series and parallel circuit?

    answer 1) a push of electrons from one place to another.
    answer 2)In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
