Calculate the power in a line having a resistance of 4 Ohms when 8 A direct-current is flowing in the line.
256 Watts
Electrical power (P) is the rate at which electrical energy is transferred or converted into other forms of energy, such as heat or mechanical work. Since A^2 \Omega is equivalent to Watts (W), the power is 256 Watts. Thus, the power dissipated in the line is 256 Watts.
