It is something like v and j say this the current I and this ZL is variable both RL and XL are variable , so that is why that is that is that is given here, impedance ZL is variable resistance and variable reactor both are variable.
તે v અને j જેવું કંઈક અહીં આપેલ છે. ઇમ્પીડેન્સ ZL એ વેરીએબલ રઝિસ્ટન્સ અને વેરીએબલ રિએક્ટર બંને વેરીએબલ છે.
