Homework Statement
Suppose a very long straight wire were held perpendicular to the plane of the page such that it intersects the page at point D. Additionally, suppose the wire was being moved toward the top of the page.
Suppose instead that the wire were moved toward the left side of the...
Thank you. Thank you for clearing up my lacking explanation that may cause misconceptions in the future. We constructed a 2.5-5 V circuit consisting of a bulb and LED in series. The bulb accounted for our current "measurement". We did a forward and reverse biased setup. In reverse, we saw that...
I want to change my answers.
First: zero.
2. all equals zero
3. LED> R1=R2=0
4. 9
But i am now confused. These answers are strictly from observation in lab. however, we did not measure currents. Is zero current correct?
Ah, I see. This is introductory university class. I believe all is assumed to be ideal. And since nothing more has been mentioned, it should be ideal. Thank you for prompt responses!
Homework Statement
Consider the circuit at right, consisting of two identical resistors (R1 and R2) and a red LED. The battery is ideal and maintains a constant voltage of +9.0 V (i.e., V1 - V2 = +9.0 V). An ideal voltmeter is connected across the LED and R2.
1. At point a, is the direction...
Homework Statement
Two identical bulbs (bulb A and bulb B), a capacitor, and a switch are connected to a battery as shown at right. The switch has been open for a long time. The battery is ideal and has a voltage (Vbat) of 4.0 volts.
The switch is now closed.
Just after the switch is...
AH! I completely overlookd the arc length. I have calculated the right answer! Thank you! Just applied the correct sign for directions of the components and it was correct. Thank you very much, RedBelly98
Ok yes, I follow. v and B and F all have direction. B is constant in this field going out of the page. Like you said, v and F are changing because B is constant. I tried also using d =vt. I can find that distance with the given time. I am now stumped with what to do with that. Parametric? hmm...
