Verify Pure resistive load's power factor is unity.

Resistive Load Resistive Loads is any electrical device that consisting of  heating element,and working based on the Resistances Working principle. Resistive loads only consumes Active Power, and does not cause changes in the value of the power factor,so the value of the power factor remains,which is equal to one. Electrical devices including resistive loads work based on the working principle of resistors,so that the electric current passing throughthem will be impeded,and as a result the electrical device will produce heat. Resistive loads do not affect voltage and current waves, so the position of the voltage and current waves remains in phase. Example of Any electrical devices that including types of resistive loads: • Incandescent lamps • Heater • Rice cooker • Electric Iron • Electric Soldering • Electric Kettles • Toasters • etc Because the electrical equipment which is included in the type of resistive load does not affect the power "factor (cosΦ = 1), The power formula of resistive is:- P= VI in watt Here, P= Power in watt, V= Voltage in volt I= Current in ampere
