Question

a battery and five resistors of equal resistance are arranged as shown in the figure below. Which resistor dissipates the most power? R_1 R_2 R_3 the power dissipated by each resistor is the same for all resistors. In figure(a) below, a solenoid produces a magnetic field whose strength increases into the plane of the page. An induced EMF is established in a conducting loop surrounding the solenoid and this EMF lights bulbs A and B. In figure(b), points P and Q are shorted (what is a wire with negligible resistance is connected across points P and Q). After the short is inserted.

Explanation / Answer

3)

R5

because current will be more from R5

4)

both bulb go out

because now current will flow from less resistance wire

****current always try to flow in less resistance wire in this case shorted wire have less resistance or no resistance

5 )

0

because out side of solenoid magnetic field is zero always.
