(a) Real Power,

ωt - 20 °) V and the current through the element in the direction of the voltage drop is i(t) = 2cos(ωt + 70 ° A.  Find the (a) real, reactive and apparent appa powers (b) power factor (c) load impedance (d) type of load.

The voltage across a load is v(t) = 50cos( $ω$ t - 20 $°$ ) V and the current through the element in the direction of the voltage drop is i(t) = 2cos( $ω$ t + 70 $°$ A. Find the (a) real, reactive and apparent appa powers (b) power factor (c) load impedance (d) type of load.
