Calculate the voltage drop in R1 and the power consumed in R2.

If R1 = 10Ω, R2 = 10Ω, and voltage = 10V, calculate the total resistance (RT), current (I), voltage drop across R1, and power consumed in R2.

If R1 = 20Ω, R2 = 5Ω, and voltage = 20V, calculate the total resistance (RT), current (I), voltage drop across R1, and power consumed in R2.

If R1 = 7.5Ω, R2 = 12.5Ω, and voltage = 24V, calculate the total resistance (RT), current (I), voltage drop across R1, and power consumed in R2.

Calculate the total current flowing in resistor R3.

Calculate the total current flowing in resistor R1.

Calculate how many turns of wire are required on the secondary (output) given: Primary voltage = 300V, Primary turns = 100 turns, output = 200V

If the load on the output side is 50Ω, what is the primary current given Primary voltage = 300V, Primary turns = 100 turns, output = 200V

As a tap changer can adjust the number of turns of a transformer, if the input of the transformer drops from 600V to 575V and needs to maintain output voltage of 230V without changing the number of primary turns (200 turns): - How many turns are now needed on the secondary? - How many turns must the tap changer be adjusted by?

What is the output of the transformer?
