Unformatted text preview: LAST NAME: STUDENT NR: PHYS 1010 6.0: CLASS TEST 5 Time: 50 minutes; Calculators & formulae provided at the end = only aid; Total = 20 points. 1) [5] Given the following circuit diagram which contains an ideal battery, and three resistors, R 1 , R 2 , R 3 . Complete the diagram by indicating how to measure: the current I 2 through resistor R 2 ; the voltage drop Δ V 3 across resistor R 3 . Then calculate the currents I 1 , I 2 and I 3 , and the power dissipated by R 3 . 1 2) [5] The diagram shows a nonideal battery (with internal resistance R int ), and a simple resistorcapacitor network. Assume that just before the switch is set from charging to discharg ing (at time t = 0) the capacitors are fully charged. Give a formula for the discharge current (without derivation, use the formula sheet which gives a generic expression). Calculate the time constant, and graph the current as a function of time (properly marked current and time axis is required!) 2 3) [5] The figure shows a straight wire segment, and then a loop. The same current passes through. Three locations are marked,through....
