GCSE Physics

How was the current affected?

To find out how the current* was affected we repeat the experiment, adding an ammeter*.

As before, the cell* has an output of 2 volts and the lamp glows moderately.
But this time we know that the current is 1 amp.

Circuit with cell and ammeter

As before, we replace the 2-volt cell with a 1-volt cell and the lamp glows dimly.

But what does the ammeter read?
