In a DC electrical circuit, the relationship between the power used by a device, P (in Watts, W), the electric potential difference (voltage), (in volts,V), the current,I (in amperes, A), and hte resistance, R (in ohms) is represented by the formulaP=IV-I^2R.

represent the relationship between the poer and the current when the electrical potential is 24V and the resistance is 1.5Ohms. Determine the current needed in order for teh device to use hte maximum amount of power.

What? as a grade 12 student i am soo lost!

Please help!
