What is the equation for current?

Understand the Problem

The question is asking for the mathematical equation that represents electric current. Current is typically defined as the flow of electric charge and is represented by the equation I = Q/t, where I is current, Q is charge, and t is time.

Answer

I = V/R

The final answer is I = V/R

More Information

The equation for electric current I = V/R is derived from Ohm's Law. It relates the current (I) flowing through a conductor to the voltage (V) across it and the resistance (R) of the conductor.

Tips

A common mistake is to confuse the symbols and units, such as using incorrect values for voltage or resistance. Remember to keep units consistent and verify values.
