Question

Physics 11th grade homework assignment For part 3 of my homework I was told Explore the circuit model below. It is a parallel circuit with an ammeter reading amp and a volt meters reading volts. The circuit has one resistor and one spaces to accommodate a second resistors. Enter an R to add resistor. Enter a X to remove a resistor. By default, the cells read "enter R for Resistor" I already completed this part (the pic below) and now I am being asked to 3. Complete each of the following parts:(a) Draw the circuit diagram for the three resistors in parallel that you assembled in Part 3. Label the voltage and the resistances of each resistor.(b) For the three resistors in parallel, how did the measured total voltage and total current compare to the values that you calculated? Use your data to support your answer.(c) How did the equivalent resistance, voltage drop across each resistor, total current, and total voltage change as you added resistors in parallel to the circuit?If u need more volt numbers I can send Resistor value (ohms) =3Power output (volts) =15

Answer 1

Diagram for part (a)

Calculations for part (b):

Each resistor individually results in a current I with a voltage V in this ratio: V = IR.

R = 3Ω and the battery voltage V = 15V. Plugging in our values for V and R,

15 = I*3; I = 5A. This value matches that of the ammeters placed right after the resistors.

The combined resistance of the three resistors in parallel can be calculated by this equation:

3*1/R = 1/Rc, where Rc is the combined resistance and R is the resistance of each of the resistors (3Ω)

3/3 = 1/Rc; Rc = 1Ω

We can use the relation V = IR to determine the resultant current when the resistance of all three resistors is combined.

15 = I*1; I = 15A. This value matches that of the ammeter placed after all the parallel loops of resistors.

(c).

When each parallel resistor was added, the values that changed were the total current and equivalent resistance. This is because each resistor adds to the total equivalent resistance across the entire circuit, which affects the total current. The values that remained constant were the total voltage (voltage does not change; only current does), and voltage drop across each resistor (each resistor had the same value, so the voltage drops equally across each one).
