A student gives a plastic strip an overall electric charge.

Describe one way that the student can give the plastic strip an overall

electric charge.

Which diagram shows the way that electric charge is now distributed?

• 
• 
• 
• 

Explain why the gold leaf has moved.

Use information from Figure 3 to give two differences between the charge on P and the charge on Q.

Object P and object Q are held near to each other so that their electric fields interact with each other.

State the effect that the electric field of object Q has on object P.

Describe the relationship between the current and the voltage as shown in the graph in Figure 4.

Use the values of the voltage and current at point P and at point Q on the graph in Figure 4 to complete the table giving information about voltage in V and current in mA at P and Q.

Calculate the resistance of the filament lamp when the voltage is 4.5V and the current is 51mA.

Use the equation:

R = V/I

Explain why the resistance of the filament lamp changes as the voltage across it increases.

Describe, in terms of particles, two differences between a solid and a liquid of the same substance.
