The diagram below shows a high-voltage supply connected across two metal plates.

When the supply is switched on, an electric field is present between the plates.

a. Explain what is meant by an electric field.

b. Copy the diagram above. Draw the electric field lines between the plates and indicate their direction by arrows.

c. The metal plates are now joined by a high-resistance wire. A charge of 0.0600 passes along the wire in 30 s. Calculate the reading on the ammeter.

d. The potential difference of the supply is re-set to 1500 V and the ammeter reading changes to 0.0080 A. Calculate the energy supplied in 10 s. Show your working.
