A

For the identical bulbs , the brightness of the bulbs depend upon the current flowing through them or the potential difference across them.

In the given circuit when the switch S is closed , due to parallel combination of bulbs B and C net resistance of the circuit decreases and hence the current through bulb A increases.While the current is divided between bulbs B and C .

Therefore the brightness of bulb A  increases , B decreases and bulb C starts glowing.

Let’s get started. https://strekatilo294.com If you do, you agree with George Herbert’s famous aphorism from his book, Outlandish Proverbs. This quote originated from Thomas Howell in New Sonnets and Pretty Pamphlets. But Yoda isn’t having it. Napoleon Bonaparte could relate. It’s easier to do it yourself rather than try to explain it to someone else. Now you might be asking. So my advice. How do aphorisms differ from adages and proverbs. Early to bed and early to rise makes a man healthy, wealthy, and wise. It reminds us to take precautionary measures, so we don’t end up with bad results. He knows that Luke should either decide that he can do it or decide to quit. Washington also said, It is better to offer no excuse than a bad one. Shifting gears a little, let’s talk about one of the world’s greatest aphorists – Benjamin Franklin. Not good. Build a storyline around that saying.
