Answer 2

Given:

A 1KΩ resistor and the current through the resistor is 4mA.

To find:

What is the voltage across a 1KΩ resistor if the current through the resistor is 4mA?

Solution:

From the given information, we have the data as follows.

A 1 kΩ resistor and the current through the resistor is 4 mA.

We are asked to find the value of the voltage across the resistor.

So, we will be making use of the Ohm's law, that is, the relation between the voltage, current and resistance.

Thus, the formula that relates the voltage, current and resistance is given as follows.

V = IR

substitute the values in the above equation.

V = 4 × 10^{-3} × 1 × 10^{3}

V = 4 V.

Therefore, the voltage across a 1KΩ resistor if the current through the resistor is 4mA is 4 V.
