Answer:

200 Ω

Explanation:

Hi there!

Please see below for the circuit diagram.

<u>1) Find the total resistance of the resistors in parallel</u>

Total resistance in parallel equation: \frac{1}{R_T} = \frac{1}{R_1} +\frac{1}{R_2}

Both the resistors measure 200 Ω. Plug these into the equation as R₁ and R₂:

\frac{1}{R_T} = \frac{1}{200} +\frac{1}{200}\\\frac{1}{R_T} = \frac{1}{100}\\R_T=100

Therefore, the total resistance of the resistors in parallel is 100 Ω.

<u>2) Find the total resistance of the circuit</u>

Now, to find the total resistance of the circuit, we must add the 100 Ω we just solved for and the 100 Ω for the other resistor placed in series:

100 Ω + 100 Ω = 200 Ω

Therefore, the total resistance of the circuit is 200 Ω.

I hope this helps!

grin007 [14]

Failure of the <u>Brake master </u>cylinder will often result in sudden unexpected loss of the ability to stop the vehicle

<u>Explanation:</u>

The ability to stop the vehicle lies with the Brakes. If brakes of a vehicle do not work properly then it might become difficult to stop the vehicle. This happens when a cylinder called brake master cylinder fails.

The brake master cylinder might not work properly with the passage of time or it can form internal leaks. This is the master cylinder and it controls other cylinders in a vehicle. Its failure affect the brakes badly, it will be unsafe to drive such a vehicle.
