ThIS IS NOT A HOMEWORK! I need to know the difference which is why i used simple setups to help ask a question. This helps me in doing more complicated circuits after understanding where a potential drop occurs and when it doesnt
I got the answer by comparing I2R of the circuit with resistor R but why do i have to use R/2 for power of resistor R?( P= (0.5I)^2 (R/2)) I know its parallel to Resistor Q but i want to find the power of that component so shouldnt it be P= (0.5I)^2 (R) instead?
How can a particle move downwards and be displaced upwards? Sounds paradoxical. I understand the part about movement but not displacement. What's the difference? Isnt displacement like the amplitude so when a particle in a transverse wave move down doesnt it mean its displaced downward?
Circuit -- Why a more accurate value of the resistance?
Note: CURRENT CAN FLOW THROUGH THE VOLTMETER IN THESE CASES.
Why does the second setup as shown by the arrow in the picture give a more accurate value of the resistance of that wire?
It says the current in setup 1 on the left measured...
when a cable car is stationary,it is in equilibrium.So the forces acting on it forms a closed triangle.(the vector diagram) Why is the triangle an isosceles triangle?
I did this question on my paper and stumbled across this on the answers,couldnt figure out why
hope someone could enlighten me!
