Calculate Short Circuit Current



Formula

The formula to calculate the Short Circuit Current (Ishort) is:

\[ I_{short} = \frac{V}{R_{short}} \]

What is a Short Circuit?

A short circuit occurs when the resistance drops to a very low value, causing a large current to flow through the circuit. This can result in overheating, damage to electrical components, and potential safety hazards. Understanding and calculating the short circuit current is essential for designing protective measures and ensuring the safety of electrical systems.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Short Circuit Current (Ishort):

\[ I_{short} = \frac{V}{R_{short}} = \frac{120}{0.1} = 1200 \text{ amps} \]

The Short Circuit Current (Ishort) is 1200 amps.
