Answer:

A voltmeter is used to measure voltage.

An voltmeter must be placed in parallel with a resistor to measure the voltage through the resistor.

An ammeter is used to measure current.

Explanation:

Voltmeter measures the voltage difference between two different points as connected in parallel not change the amount of current going through the element between those two points. So, an ideal voltmeter has very high resistance so that it doesn't "draw" current through it i.e loading effect.

Ammeter has almost negligible or very small resistance. As a result, it must be connected in series so that as much current can pass through it as possible. If it is connected in parallel, the circuit will be shorted and no current will pass through any electrical components connected in the circuit.

Answer:

A) True. Voltmeters measure voltages

C) True. They are placed in parallel

E) True ammeters are used to measure current

Explanation:

The devices for voltage measurement are the voltmeter and ammeter

Voltmeters have very high intense resistance and are placed in parallel

The ammeters have very small resist and are placed in series

Based on this establishment, let's analyze the statements

A) True. Voltmeters measure voltages

B) False has high intense resistance

C) True. They are placed in parallel

D) False ammeters are placed in series

E) True ammeters are used to measure current

F) False ammeters have a low internal resistance

What would happen if organ systems failed to wok together
ira [324]
<span>Our body shape, production of red blood cells, and the protection of major organs in the body are all in the performance of the skeletal system. Supplying our blood oxygen, if this system fails our body will cease to function entirely from the lack of oxygen and the carbon dioxide filling us inside.</span>

A spring has an unstretched length of
koban [17]

Answer:

24 N

Explanation:

Given,

Unstretched length or original length , x1 = 12cm

Stiffness constant, k = 8 N/cm

Load required to take spring to a length , x2 of 15cm

Recall the relation :

F = Ke

Where, e = extension

e = x2 - x1

e = (15 - 12) = 3

F = ke

F = 8 N/cm * 3cm

F = 24 N/cm*cm

F = 24 N

Hence, required load = 24 N
