According to Ohm's law what would happen to the current if resistance was increased?

Answer 1

according to the ohm's low if we increase the resistance the current decreases. As ohm's low states voltage is directly proportional to the current and resistance. So current can defined as the ratio of voltage to the resistance, as large the resistance, as low the current.

Answer 2

the effect of cutting the resistance have on the current is that the current will increase its voltage because only the resistance will hold the current from passing through directly in a certain objects.

Answer 3

V = iR is Ohm's law, where V is voltage, i is current, and R is resistance.

If i goes up, but R stays the same, then V will go up, as V and i are directly proportional.

How is this in the "Environmental Issues" category?

Answer

Ohm's Law states that 'the current flowing through a conductor, at constant temperature, is directly proportional to the potential difference across the ends of that conductor'.

For Ohm's Law to apply, the ratio of voltage to current must be constant over a wide range of changes in potential difference. In other words, the resistance must remain constant over a wide range of changes in potential difference. As this is the case with your question, a doubling in current would double the potential difference appearing across the resistor, and so on.

Note that the equation R = V/I is derived from the definition of the ohm, has nothing to do with Ohm's Law, and applies whether Ohm's Law applies or not.
