Why was before used the 300 ohm transmission line?
The impedance of a centre fed dipole at resonance is about 73 ohms. The feed impedance of a folded dipole is four times that, 292 ohms. The feedpoint is of course balanced in both cases, thus 300 ohm balanced line is an excellent match for the folded dipole active element of a commercial TV antenna.
Why is a set up transformer needed in a stereo or tv set?
A stereo or tv set needs a step-up transformer because a step-up transformer increases the voltage of an appliance and a stereo or and a tv set needs a high voltage.-------Semper Fidelis(ADC)----------
What is the ideal value of input resistance?
depends on what you are measuring practical use like electricity or batteries as low as possible to test voltage on a car battery perhaps 0.1 ohm / volt to check the final anode on a crt tv at least 1000 ohms per volt low power circuits require higher impedance wire connections low impedance the 10000 ohm per volt meters are fine as fixed monitors but usless for practical service work. they indicate voltage thru oxides and lose screws they show 120V in a socket when the lamp refuses to light
An old television draws about 3 A of current It plugs into a wall outlet that is 120 V What is the resistance in ohms of the television?
Is this, intentionally, a trick question?We are dealing with alternating current, here, not direct current. So, if you divide the supply voltage by the current drawn by the television set, you are determining its impedance(Z), not its resistance:Z = V/I = 120/3 = 40 ohmsImpedance is the vector sum of resistance and reactance. As the current is probably being drawn by a transformer, the resistance will be significantly lower than the reactance, perhaps only an ohm or two -if that!So, from the information supplied, you cannot determine the resistance.
