Part A: Go with The Flow 1. A 5.0 C charge flows through a wire in 3 s. Calculate the current. 2. A nichrome wire of length 1.5 m is used as conductor. The cross-sectional area of the wire is 0.75 m2. Calculate for the resistance of the nichrome wire. (Resistivity of nichrome is 1.00 x 10'5 Q) 3. A 5.0 A current is drawn to the circuit with resistor 5.0 -Q. What is the voltage of the source? 4. In a physics laboratory experiment where a Data Table of Voltage and student varies the voltage across a long straight Current in a Wire wire. the current was measured at each voltage value of the voltage source. The result is shown in the table. Trial V (volts) I (amperes) 1 0.50 What conclusion best describes the data? 2 1.00 A. The wire observes Ohm's Law at voltage 3 150 value between 5.0 V to 25.0 V. B. The wire observes Ohm's Law throughout 4 2'00 any voltage value. 5 2.50 C. The current is directly proportional to voltage 6 300 253 applied. D. The resistance of the wire is directly 7 35'0 2'78 proportional to the voltage applied
