(a) increase the length of the wire or increase the area across the (b) increase the length of the wire or decrease the (c) decrease the length of the wire or increase the area across (d) decrease the length of the wire or decrease the area across the wire wire area across the wire (2 pts each) 7a) Which of the following statements is Kirchhoff's current rule 7b) Which of the following statements is Kirchhoffs voltage rule A) total voltage into a junction must equal the total voltage out of the junction B) the sum of the voltages around a loop must equal zero C) total current into a junction must equal the total current out of the junction D) the sum of the currents around a loop must equal zero 8(2 pts) The two resistors in the circuit shown to the right are: ?in series b) in parallel c) in combination For problems 9-12 (6 points each), you need to SHOW YOUR WORK, and may get partial credit if your work demonstrates your understanding of the concepts Clearly indicate your final answer!!! 9) An nylon-filled capacitor consists of two parallel plates, separated by a distance of 2.00E-4 m and each with an area of 0.0500 m2 hat is the capacitance of this capacitor? . The dielectric constant is 3.4 for nylon.

Explanation / Answer

Ans5.

current always flow through the opposite of electrons moving

Hence the direction of current will flow in the left direction.

ANS 06

R = row * L/ A

From above relation we can easly find that resistanc eof the wire is directely propertional to the lengnth and invesly of the area of crossection.

Hence resistance can decrease by decreasing the length and increasing the cross sectional area.

Option C is right ans

7 (a)

option B

7(B)

Option (C)

ans 8

Bothe resistance are connected in series because there same current flowing through it.

Option A.

Hope it will help you. please rate the answer.
