What is the effect on the current in a wire if
both the voltage across it and its resistance
are doubled?
1. The current does not change.
2. The current is 4 times bigger.
3. The current is doubled.
4. The current is reduced to a quarter of its
original value.
5. The current is halved.
6. It cannot be determined.
