If I=1 amp and R=10,000 ohms, what is the voltage?

To find the voltage, you can use Ohm's Law, which states that Voltage (V) = Current (I) × Resistance (R). In this scenario, the current (I) is given as 1 amp and the resistance (R) is 10,000 ohms.

By substituting the given values into the formula:

V = I × R V = 1 amp × 10,000 ohms V = 10,000 volts

This calculation shows that when a current of 1 amp flows through a resistance of 10,000 ohms, the resulting voltage is indeed 10,000 volts.

Understanding this concept is crucial as it highlights the direct relationship between voltage, current, and resistance in electrical circuits. The larger the resistance for a given current, the higher the voltage required to drive that current through the resistance.
