A λ/2 dipole, with a total loss resistance of 1 ohm, is connected to a generator whose internal impedance is 25 + j25 ohms via a 50-ohm λ/2-long lossless transmission line. Assuming that the peak voltage of the generator is 2 V and the impedance of the dipole, excluding the loss resistance, is 73 + j42.5 ohms, find the power a) supplied by the source (real) b) radiated by the antenna c) dissipated by the antenna
Draw a circuit with a resistance(R=V/I) of 1500 ohms, but you only have access to 1 resistor of 1000 ohm. Hint: use exactly 3 resistors. Use wires, switches, battery, voltmeter, and ammeter, regular resistors of 10 ohms. You can change your resistor value. Do this by using equivalent resistance equations for both series and parallel.
A 12 ohm, a 15 ohm, and an unknown resistance are connected in parallel. The total current of the combination is 12 A. The current across the 15 ohm branch is 4 A. What is the total voltage? What is the total resistance? What is the unknown resistance?
For the following circuit, assume that R1 = 1 ohm,
R2 = 2 ohms, R3 = 8 ohms, and R4 =
4 ohms. Also assume that V1 = 50 volts and V2
= 100 volts. Find the current through each of the resistors and the
power dissipated through all of the resistors. (Hint: You’ll need
to use Kirchoff’s Loop and Junction Rule)
