Following figure shows an `AC` generator to a "block box" through a pair of terminals. The box contains possible `R,L,C` or their combination, whose elements and arrangements are not known to us.

Measurements, outside the box reveals that `e=75 sin(omega t) `volts, `i=1.5 sin(omegat+45^(@))` amp then. the wrong statements is

Following figure, as shown an an generator connected to a "block box" through a pair fo terminal.The box contains possible R,L,C of their combination, whoe elements and arrangements are not known to us. Measurements outside the box revals that e=75sin(ωt) volts, i=1.5sin(ωt+45∘) amp then. the wrong statements is

An a.c. generator is connected to a sealed box through a pair of terminals. The box may cantain R,L,C or series combination of any two of the three elements. Measurements made outside the box show that E = (75 sin omega t) volt and I = 1.2 sin (omega t + pi//5) A (i) Name the circuit elements (ii) What is the power factor of the circuit (iii) What is the rat at which energy is delivered by the generator to the circuit ?

An alternating voltage is connected to a box with some unknown circuital arrangement. The applied voltage and current through the circuit are measured as (v = 80 sin omega t) volt and (i = 1.6sin(omega t + 45^0) ampere: Is the circuit in the box largely capacitive or in ductive?

An alternating voltage is connected to a box with some unknown circuital arrangement. The applied voltage and current through the circuit are measured as (v = 80 sin omega t) volt and (i = 1.6sin(omega t + 45^0) ampere : Is the circuit in the box at resonance?

An alternating voltage is connected to a box with some unknown circuital arrangement. The applied voltage and current through the circuit are measured as (v = 80 sin omega t) volt and (i = 1.6sin(omega t + 45^0) ampere : What is the average power delivered by the box?

An alternating voltage is connected to a box with some unknown circuital arrangement. The applied voltage and current through the circuit are measured as (v = 80 sin omega t) volt and (i = 1.6sin(omega t + 45^0) ampere: Does the current lead or lag the voltage?

A combination of elements is enclosed in a black box an the voltage and currents are measured across this black box. The expression for applied voltage, and the current flowing in it is V = V_(0) sin omega t , i = 2 sqrt(2) sin (omega + pi//4) where omega = 100 pi "rad"//"sec" Then the wrong statement is

In a black box of unknown elements (L or R or any other combination), an ac voltage E=E_(0) sin (omegat)+phi) is applied and current in the circuit was found to be I=(I_0) sin [ omega t + phi + (pi//4)] . Then the unknown elements in the box may be
