\nThe power (P) of an electrical device is given by the product of the voltage (V) across it and the current (I) flowing through it. Given V = 110 V and I = 0.2 A, the power is P = V \u00d7 I = 110 V \u00d7 0.2 A = 22 Watts.
\n<\/section>\n
\nElectrical power (P) is calculated using the formula P = VI, where V is the voltage in volts and I is the current in amperes. The unit of power is the Watt (W).
\n<\/section>\n
\nOther useful formulas relating power, voltage, current, and resistance (R) are P = I\u00b2R and P = V\u00b2\/R (derived from Ohm’s Law, V=IR). In this problem, only voltage and current were given, so P=VI is the direct formula to use.
