Three resistors R1, R2 and R3 are connected in series-parallel. R1 is in series with the parallel combination of R2 and R3. The whole combination is connected across a 120 V DC source. Resistors R1, R2 and R3 take 750 W, 250 W, and 200 W, respectively. Calculate the resistance R2.
A 10-ohms and a 20-ohms resistors are connected in parallel. Another resistor of 5-ohms is connected in series with the two. If the supply voltage is 48 volts, what is the current through 10-ohm resistors? Use Current Division Theorem.
A 5-ohms resistor is connected to a series combination of a two resistors, 10 ohms and 15 ohms. Calculate the total current when connected to 24 V DC source.
