If the resistance in a circuit connected to a constant current is halved, how is the voltage in the circuit affected?.

Sagot :

Answer:

The voltage remains constant.

Answer:

The voltage in the circuit remains same. However the current drawn by the circuit will increase.

Explanation:

According to Ohm's Law:

V=IR

If we halved the resistance let:

R'=R/2

then

I'=2I in order to kept the Voltage same. Also the resistance is the opposition to the current. So, if resistance will halved then obviously current will double

So when we put these value in to Ohm's Law the results is:

V'=I'R'

V'=2I(R/2)

V'=IR which is equal to first voltage. Hence,

V'=V
