what will happen to current passing through a resistance, if potential difference across it is doubled and the resistance is halved .............

But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current. If there is no other resistance in the circuit and the power supply can handle it, halving the resistance doubles the current.Using Ohm's law, for constant potential difference, we may write: I∝R1 So, if the resistance is doubled, current becomes half. If the potential difference across the ends of a conductor is halved the current flowing through it also gets halved. ... Therefore,if the resistance of the conductor is doubled,the current gets halved. The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel. Electrical resistance shows how much energy one needs when you move the charges/current through your devices.
