What would the total current be if the voltage across a 10 ohm resistor is 80V?

To determine the total current flowing through a resistor when given the voltage across it, you can use Ohm's Law, which states that current (I) is equal to the voltage (V) divided by the resistance (R). The formula can be expressed as:

[ I = \frac{V}{R} ]

In this situation, the voltage (V) is 80 volts and the resistance (R) is 10 ohms. By substituting these values into the equation, you can calculate the current:

[ I = \frac{80V}{10\Omega} = 8A ]

This calculation indicates that the current flowing through the 10 ohm resistor with a voltage of 80V is 8 amperes. This conclusion is consistent with the fundamental principles of electrical circuits and provides a clear understanding of how voltage and resistance interact to determine current.
