This is a ....

• series circuit

• parallel circuit

• neither

• A₁

• A₂

• A₃

• A₄

• None of them

The left hand bulb blows. What happens to the brightness of the right hand bulb?

• It increases a little

• It decreases a little

• It increases a lot

• It decreases a lot (it switches off in fact)

The bulbs have difference resistances. What can be said about the current and voltage

• Current is the same in both bulbs, voltage is different across each

• Current is the same in both bulbs, voltage is the same across each.

• Current is different in both bulbs, voltage across each is the same

• Current is different in both bulbs, voltage across each is different too.

Which bulbs are on if S₁ is open and S₂ and S₃ are closed?

• B₁ off, B₂ off, B₃ off

• B₁ on, B₂ off, B₃ off

• B₁ off, B₂ on, B₃ on

• B₁ on, B₂ off, B₃ on

If V₂ is greater than V1, what can we conclude?

• B₁ has a higher resistance and is dimmer

• B₂ has a higher resistance and is dimmer

• B₁ has a lower resistance and is dimmer

• B₂ has a lower resistance and is dimmer

If the top bulb has a higher resistance what can you say about the current?

• A₁ > A₂ > A₃

• A₁ > A₃ > A₂

• A₁ = A₂ = A₃

• A₂ = A₃
