Ohm's law states that V=IRV=IR for a simple circuit, where VV is the total voltage, II is the amount of current running through the resistor and RR is the resistance of the resistor. If I=40I=40 amperes when R=3R=3 ohms, find the amount of current (in amperes) when the resistor has a resistance of 2020 ohms. Assume voltage remains constant.

Original LaTeX notation
Ohm's law states that $V=IR$ for a simple circuit, where $V$ is the total voltage, $I$ is the amount of current running through the resistor and $R$ is the resistance of the resistor. If $I=40$ amperes when $R=3$ ohms, find the amount of current (in amperes) when the resistor has a resistance of $20$ ohms. Assume voltage remains constant.
