What Is the Current Distribution in a Parallel Circuit with Three Loads?

[swathi]

A current of 4.80 A leaves a battery and separates into three currents running through three parallel loads. The current to the first load is 2.50 A, the current to the second load is 1.80 A, and the resistance of the third load is 108 [resistance sign here ] .

calculate (a) the equivalent resistance for the circuit
(b) the resistance of the first and second loads

=)
please and thankyouu !
TEST TOMORROW :|

Please show some work and effort. What is the relationship among, voltage, current and resistance? What is the significance of the voltage across parallel loads?

Hello,

Thank you for sharing the information about the grade 11 parallel circuit test tomorrow. It is important to prepare and study for tests to ensure a good understanding of the material.

To answer your question, let's first define some terms. Equivalent resistance refers to the total resistance of a circuit when all the individual resistances are combined. The formula for calculating equivalent resistance in a parallel circuit is 1/R = 1/R1 + 1/R2 + 1/R3, where R1, R2, and R3 are the resistances of the individual loads.

(a) To find the equivalent resistance for this circuit, we can plug in the given values into the formula:
1/R = 1/R1 + 1/R2 + 1/R3
1/R = 1/108 + 1/108 + 1/108
1/R = 3/108
R = 108/3 = 36 [resistance sign here]

(b) The resistance of the first and second loads can be found by using Ohm's law, which states that resistance is equal to voltage divided by current (R=V/I). We know the current (2.50 A and 1.80 A) and we can assume a standard voltage of 1 volt, so we can calculate the resistance for each load.
R1 = 1/2.50 = 0.4 [resistance sign here]
R2 = 1/1.80 = 0.56 [resistance sign here]

I hope this helps with your preparation for the test tomorrow. Good luck!
