What is the current through a 24-ohm resistor connected across 240 volts?

To find the current through the resistor, you can use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). In this case, the voltage across the 24-ohm resistor is 240 volts.

Using the formula:

I = V / R

Substituting the given values:

I = 240 volts / 24 ohms

Calculating this gives:

I = 10 amperes

This calculation shows that when a voltage of 240 volts is applied across a 24-ohm resistor, the resulting current is indeed 10 amperes. Understanding how to apply Ohm's Law is fundamental in electronics and helps in calculating the behavior of circuits with different resistances and voltages.
