Which of the following will increase if the voltage in a circuit is increased? check all that apply

a.) current

b.) resistance

c.) heat produced by the circuit

d.) magnetic force

If the voltage in a circuit is increased then the current, heat and magnetic force will be increase.

Option (a),(c) and (d) is correct.

Explanation:

According to Ohm's law

Current :

The current is directly proportional to the voltage .

So, the current will increases then the voltage will be increase.

Resistance :

The resistance does not depend on the voltage because the resistance depends on the length of the wire, radius and the resistivity of the wire.

Heat :

Heat depends on the power and power depends on the voltage and current.

So, when the voltage will increase in the circuit then the heat produced by the circuit would also increase.

Magnetic force

When the current flows in the wire then magnetic field is produced around it. If the current increases then magnetic field increases. This would increase the magnetic force associated with it.

Hence, If the voltage in a circuit is increased then the current, heat and magnetic force will be increase.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
