1. 36 C оf chаrge flоws thrоugh а conductor in 1.2 s when 12 V is аpplied across it. A. What is the current (assumed constant) in the conductor? (4 pts) B. What will be the current if the voltage is increased to 18 V? (5 pts) A 3.0 m long wire with a cross-sectional area of 0.025 m^2 has a current of 1.5 A when 9.0 V is applied across it. What is the resistivity of the wire? (10 pts) A conductor has 1.3 A of current flow through it when 9.0 V is applied across it when it is at a temperature of 20⁰ C. When the temperature is increased to 80⁰ C, the current decreases to 0.75 A when 9.0 V is applied. What is the temperature coefficient of the conductor? (10 pts) 4. A simple circuit has a total resistance of 30 Ω. If a 2.0-A current is maintained in this circuit A. How much power is delivered to the circuit? (4 pts) B. How much energy is dissipated in this circuit in 4.0 seconds? (5 pts) 5. A 2.5 m long wire with an area of 0.36 m^2 wire has 1.5 A flow through it when 10 V is applied across it. A. How much power is delivered to the wire? (4 pts) B. How much power would be delivered to the wire if it were half the length? (5 pts) For the circuit shown find: a) the equivalent resistance (5 pts) and b) the current in each resistor (10 pts). The voltage of the battery is 20 V. Two capacitors (C1 = 3 uF and C2 = 4 uF) are hooked in parallel to a 20 V battery. If a third capacitor is to be added in order to increase the energy by 30%, A. In what way should it be hooked in? (series or parallel) (4 pts) B. What should be the capacitance of this capacitor? (6 pts) For the following circuit R1 = 0.6 Ω, R2 = 6 Ω, R3 = 7 Ω and the voltage of the batteries is V1 = 10 V and V2 = 10 V. Find the current in each resistor. (11 pts) A capacitor of capacitance C = 4 mF is initially charged by a 20 V battery. It is then discharged through a resistor of resistance R = 4 kΩ. A. Calculate the time constant. (3 pts) B. Calculate the maximum charge stored on the capacitor. (3 pts) C. Calculate the maximum current that passes through the resistor. (3 pts) D. How long will it take for the capacitor to lose half its initial stored charge? (4 pts) E. What current will flow through the resistor when the charge on the capacitor has dropped by 70 %? (4 pts)
