A battery of 100V is connected across a resistor and causes a electric current of 5 mA to flow. Determine the resistance of the resistor. If the voltage is now reduced to 25 V, what will be the new value of the current flowing?

Step 1
Ohm's Law states that V = IR, where V is the voltage across the resistor, I is the current through the resistor, and R is the resistance. We can rearrange this formula to solve for R: R = V / I. Show more…
