): The electrical potential difference or "push" provided by a source like a dry cell. It is measured in . Current (

What happens to the current if the voltage is halved but resistance stays the same? ) is directly proportional to Voltage ( ), so current is also halved. Which is a better conductor: Iron or Mercury? Iron, because it has lower resistivity than mercury. ✅ Summary of Formulas f2 science electricity exercise top
