QUESTION 1

A 10 cm long piece of wire with a diameter of2 mrn has a voltage across it of 2 V and current through it of l1 . Another wire made of the same material but with twice the length (20 cm) and half the diameter (1 mm) has the same voltage across it of 2 V and has a current through it of |2. What is the ratio of I1 to lg, |1l|2? 0118 0114 0112 O2 04 08 QUESTION 2 Consider two resistors, R1 and R2, that have different resistances. Determine what must be the same for both resistors when they are in parallel or in series. » v In series? A. Both current and voltage » V In parallel? B. Voltage c_ Current D. Neither current nor voltage QUESTION 3 It you want to measure the voltage across a circuit element using a voltmeter, how should the voltmeter be connected to the circuit element? 0 The voltmeter should be in parallel with the circuit element 0 The voltmeter should be in series with the circuit element 0 The voltmeter can be either in parallel or series
