What would happen if the voltage impressed across a circuit is held constant while the resistance doubles

What would happen if the voltage impressed across a circuit is held constant while the resistance doubles.

The answer is:

A change will occur in the current which is, "The new current will be half the initial value."

Explanation:

Voltage, also called electromotive force,  is the measure of specific potential energy between two locations in an electrical field.

V= IR

Where, V= Voltage

             I= Current

             R= Resistance

The greater the voltage in a circuit, the greater its ability to push more electrons and do work.

Voltage is measured in volts (V). Voltage is the difference in charge between two points, and can also be considered as the pressure that forces the charged electrons to flow in an electrical circuit.

Current is the rate at which charge is flowing. An electric current flows when electrons move through a conductor, such as a metal wire.

Resistance is a material's tendency to resist the flow of charge (current).  Resistance is measured in ohms, and can be further explained as a measure of the opposition to current flow in an electrical circuit.  Resistance is good because it protects humans from the harmful energy of electricity.  Resistance, R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A).

Current is directly proportional to the voltage and inversely proportional to the resistance.

If voltage is increased, the current will also increase. The higher the resistance, the lower the current flow. The lower the resistance, the higher the current flow.

Doubling the voltage will cause the current to be doubled. Also, doubling the resistance will cause the current to be one-half the original value.
