The voltage drop across a 20 Ω resistor with 10 A flowing would be _____ V.

To determine the voltage drop across a resistor, you can use Ohm's Law, which states that the voltage (V) across a resistor is equal to the current (I) flowing through it multiplied by the resistance (R). The formula is V = I × R.

In this scenario, the resistance is given as 20 Ω and the current flowing through the resistor is 10 A. By substituting these values into Ohm's Law, you calculate the voltage drop as follows:

V = 10 A × 20 Ω = 200 V.

This calculation clearly shows that the voltage drop across the 20 Ω resistor with a current of 10 A flowing through it is 200 volts. Hence, the correct answer reflects the direct application of Ohm's Law, confirming that the voltage drop is indeed 200 V.
