Answer:

False

Explanation:

A turbine is a machine formed by a wheel with several propellers. By continuously receiving a liquid in its central part, the turbine expels to its circumference and can harness its energy to generate a driving force.

Although turbines are very efficient, some failures can always come up, so it is not correct to say that turbines are 100% efficient.

In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance. What is the total resistance?

Sauron [17]

Answer:

17 ohms

Explanation:

Given that,

In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance.

We need to find the total resistance of the circuit.

The equivalent resistance for series combination is given by :

$R_{eq}=R_1+R_2+....$

For 17 light bulbs, the equivalent resistance is given by :

$R_{eq}=R+R+....\text{upto 17 terms}\\\\R_{eq}=17R\\\\=17$

Hence, the total resistance is 17 ohms. Hence, the correct option is (d).
