how do i do it?

Answer 6

thanks

Answer 7

Hi! I can help :)

You know that electrical potential is greatest at the positive terminal, and goes to \(0\) at the negative terminal as a reference, right?

You also know that the voltage (energy per charge) will drop as electrons lose energy due to resistance, right? Or, at the least, you know resistors cause a "voltage" drop.

Lastly, the connections are assumed to have no resistance, and so no voltage drop.

Those are the principles that will help you mark the voltage from X to Y.

Is that helpful?

Answer 8

Ohhhhhh! One more thing.

A greater resistance implies a greater "voltage drop."

Answer 9

(More resistance means more energy lost through the resistor.)

Answer 10

The steeper drop is the more dramatic voltage loss. So, you look at the order of those, too.

Answer 11

and how exactly can i come to the correct answer

Answer 12

So, start at X. You have have the starting voltage at that point because there's no resistance at that point, right?

Answer 13

@thushananth01 ?

Answer 14

yes

Answer 15

v at x will be maximum, so less voltage drop through resistor X and the gradient would be less steeper, and then no voltage drop trough the connections and then more voltage drop through resistor Y which would produce a more steeper gradient.. therefore D the answer it is>

Answer 16

Yep!

Answer 17

thanks alot..mind helping me with another question?
