Question

Extensive Physics help; I have a problem

Answer 1

1. When the switch is thrown closed, the value of voltage across R1

Answer 2

2. When the switch is thrown closed, the value of the current through R1:

Answer 3

When the switch is open, what kind of circuitry is this, series or parallel?

Answer 4

What does parallel mean
But I know it's Parallel

Answer 5

It actually isn't parallel

Answer 6

Wait what

Answer 7

High effort drawing

Answer 8

I'm really proud of you

Answer 9

Answer 10

So I bsed this assignment right
and number one needed an explanation
I said
"Voltage increases of cars'

Answer 11

Okay so the thing with series is that the current is constant across the circuit. When the circuit is parallel, instead, voltage is constant throughout the circuit.

Answer 12

This is what changes when you flip that switch.

Answer 13

Because it controls whether if the circuit is parallel or series.

Answer 14

I-
what

Answer 15

Okay continue

Answer 16

I gave you the key to solving this problem

Answer 17

How tf

Answer 18

Hey, are you given the values of the resistances?

Answer 19

\[V = i\left(R_1 + \frac{R_2 R_3}{R_2 + R_3}\right) \implies i = \frac{V(R_2 + R_3)}{R_1 R_2 + R_1 R_3 + R_2 R_3}\]And now the voltage across \(R_1\) is expressed by the product of the current times the value of the resistance (Ohm's law), and that is equal to\[V_{R_1} = iR_1 =\frac{VR_1(R_2 + R_3)}{R_1 R_2 + R_1 R_3 + R_2 R_3} \]

Answer 20

Here, I assumed that the two parallel resistances are \(R_2\) and \(R_3\) (order doesn't matter).
