Choose true or false for each statement regarding the resistance of a wire. O While maintaining a constant voltage V, the current I increases when the resistivity p of a wire decreases. While maintaining a constant voltage V, the current I increases when the cross-sectional area A of a wire expands. The resistance is inversely proportional to the cross-sectional area A of the wire.

Problem 7: a) What is the net resistance (Req) of the circuit connected to the battery in the following figure? (Hint: give your answer in term of R) R www R B www R C www R V R R A b) If R = 8/13 Ohms, what is the value of Req?

In the figure below, what is the net resistance of the circuit connected to the battery? Each resistance in the circuit is equal to 5.7 kΩ.

In the circuit shown below, Vs = 60 V, R1 = 7 Q, R2 =10 V, R3 = 6 Q and R4 = 6 Q. The Thevenin equivalent of this circuit consists of a voltage source Vth and series resistance RTh. FInd Vth and Rth and hence determine the current that will flow through a 50 Q resistor connected between points A and B. Give your answer in Amps to three decimal places.

Three resistors are connected in parallel. The resistances are each worth R1 = 2 ohms, R2 = 1 ohm and R3 = 2 ohms. If the resistance circuit is connected to a voltage of 12 volts, calculate the total current and the current flowing in the 1 ohm resistance. a. The magnitude of the total current = 14 A; current strength at R2 = 12 Ab. The magnitude of the total current = 24 A; current strength at R2 = 12 Ac. The magnitude of the total current = 18 A; current strength at R2 = 14 Ad. The magnitude of the total current = 20 A; current strength at R2 = 14 A
