The voltage in a circuit can be found using Ohm's Law, which states that voltage (V) equals the current (I) multiplied by the resistance (R): V=I×RV=I\times RV=I×R. Given the current of 20 amperes and the resistance of 12 ohms, the voltage is:
V=20 A×12 Ω=240 voltsV=20,\text{A}\times 12,\Omega =240,\text{volts}V=20A×12Ω=240volts
So, the voltage across the load is 240 volts.
