Please Help me with my homework problems.
D FG Problem 6. A length of wire is cut in half and two length are wrapped together side by side to make a thicker wire. How does the resistance of this new combination compare to the resistance of the origin wire?
a piece of copper wire of resistance R is cut into 10 equal lengths. These parts are connected in parallel. How does the joint resistance of the parallel combination compare with the original resistance of the single wire? The circuits, P and Q, show two different ammeter-voltmeter methods of measuring resistance. Suppose the ammeter has a resistance of 0.10 ohms and the voltmeter of 3.0 ohms; the ammeter reads 2.5 amps and the voltmeter reads 6.0 volts. What is the...
4. A copper wire of resistance 16 12 is cut into four equal pieces that are then placed together side by side to form a new cable with a length equal to 1/4 the original length. What is the resistance of this new cable? a) 16 22 b) 122 c) 422 d) 16/9 22 e) none
A piece of wire has a resistance R. It is cut into two pieces of equal length, and the pieces are twisted together parallel to each other. Part A What is the ratio of the resistance of the resulting wire to R?

17. (I) Compute the voltage drop along a 21-m length of household no. 14 copper wire (used in 15-A circuits). The wire has diameter 1.628 mm and carries a 12-A current.
Please draw detailed pictures!!!
3. (II) What is the internal resistance of a 12.0-V car battery whose terminal voltage drops to 8.8 V when the starter motor draws 95 A? What is the resistance of the starter?
Please write clearly.

44, (II) How strong is the electric field between the plates of a 0.80-μF air-gap capacitor if they are 2.0 mm apart and each has a charge of 62 pC?
Two pieces of 14-gauge wire (diameter=0.163cm) each are 50m in
length. One wire is made of aluminum, the other of tungsten; both
are maintained at a temperature of 20°C. The wires are joined
together at one end to form a sign wire of 100m length. A potential
difference of 12V is applied across the length of this compound
wire. (a) What is the resistance of each 50m segment? (b) What is
the current in each? (c) What is the potential...
Consider a wire 1.00 meters in length with 0.100 mm diameter and resistivity, ? = 1.18 x 10’(Ωm. Give all calculated answers to 3 significant figures and report voltages in millivolts. a) (10 pts) Calculate the resistance of the wire. ?)*+, = ________________________ b) (10 pts) The same wire is placed in an AC voltage divider circuit with a function generator. It follows, in series, a resistor, R=5.00 kΩ. An oscilloscope’s channel one shows a 9.10 peak-to-peak voltage sine wave...
