According to Ohm’s law, across a resistor with constant resistance, what happens to the current across it when the voltage applied is halved?
Verified answer
Answer:
The current will be halved.
According to Ohm's law, the current is inversely proportional to the resistance while directly proportional to the voltage.
So, this means that the current will also be halved, since the voltage is halved, and resistance remains constant.
If, for example, the voltage is increased, the current will also increase, but, when the resistance is increased, the current will decrease.
Hope this helps!
