Calculation of Total Resistance:

To find the total resistance of the circuit, we need to calculate the equivalent resistance of the three resistors connected in parallel. The formula for calculating the equivalent resistance of resistors in parallel is:

1/R_total = 1/R1 + 1/R2 + 1/R3

Given that the resistances of the three resistors are 10 Ω, 15 Ω, and 30 Ω, we can substitute these values into the formula:

1/R_total = 1/10 + 1/15 + 1/30

Simplifying the equation, we get:

1/R_total = 3/30 + 2/30 + 1/30 = 6/30 = 1/5

To find the total resistance, we take the reciprocal of both sides of the equation:

R_total = 5 Ω

Therefore, the total resistance of the circuit is 5 Ω.

Calculation of Current in Each Resistor:

To calculate the current flowing through each resistor, we can use Ohm's Law, which states that the current (I) flowing through a resistor is equal to the voltage (V) across the resistor divided by its resistance (R):

I = V/R

Given that the voltage applied to the circuit is 36 V, we can calculate the current flowing through each
