Answer:

100 watt

Explanation:

In parallel the 100w bulb will glow brighter.

The 100w bulb has a lower resistance of the two. That’s why it uses more power normally.

In series, the same current must flow through the two bulbs. And beacuse the power in each bulb is proportional to the resistance, keeping the current constant, the bulb with the highest resistance will glow brightest.

Ignoring the effect of the heat if the filaments. As the resistance in the glowing wire increases with temperature, the bulb with the highest resistance will glow proporitionally more than the power difference suggests. Likely the 100w bulb will not glow at all.

What is a difference between systemic and pulmonary circulation
serious [3.7K]

<u>Answer</u>:

The difference between systemic and pulmonary circulation is the Systemic circulation carries the blood between to the heart and body and the pulmonary circulation carries blood  between the lungs and the heart.

<u>Explanation</u>:

Circulation of blood is of two types:  

The systemic circulation and The pulmonary circulation.  

The Systemic circulation carries the oxygenated blood from heart to the body through the arteries (aorta) and also carries back the deoxygenated blood from the body to the heart through veins (superior vena cava) and pulmonary circulation carries deoxygenated blood to the lungs from the heart and from the lungs to the heart.

In Pulmonary circulation the pulmonary artery is used to carry the deoxygenated blood to the lungs and the pulmonary vein is used to carry oxygenated blood to the heart from the lungs.
