Current Attempt in Progress The drawing shows a straight wire carrying a current I. Above the wire is a rectangular loop that contains a resistor R. If the current / is decreasing in time, what is the direction of the induced current through the resistor R-left-to-right or right-to-left? If the induced current goes from left to right through the resistor, type the letters "LTR" in the box below. If the current goes from right to left through the resistor, type the letters "RTL" in the box. Direction of induced current -

Answer all the questions You have 6 PV panels that each have the same I-V curve (ISC = 5.5 A, VOC = 45 V). (a) How many connection configurations that use all 6 panels are possible? Draw each one. (b) Draw the I-V curves for each of the configurations on one graph. You may draw the curves by hand or use a software of your choice. Clearly label each curve. (c) Assume you are to power a 2.5 Ω load with the panels. Knowing that dimmer sunlight reduces the current output of the cells but not the output voltage, what configuration would be best if you were to build it? Explain your answer.
Clear Explanation on this question add some step to leading to this how you get this answer neat handwriting and clear explanation difficult so please double check answer have a 2m rod that has been charged to 4C, and a 1m rod that has been charged to -6C. can place them anywhere on the x-axis (i.e. they are parallel to the x-axis) subject to the following rules: • The rods cannot be touching. • The rods cannot occupy the same space. a) Draw your system on a Cartesian plan (with labeled axes). b) Pick any point on the axis that is not being occupied by the rods. Clearly label it. c) Determine the field at this point. d) Determine the voltage at this point.
