Question 1: If the current is 1.07 mA at an applied voltage of 606 mV, and the current is 4.05 mA at an applied voltage of 640 mV, what is the ideality factor? You can assume that the thermal voltage is 0.0259V. Answer should be to three significant digits with fixed point notation. Correct Answer: 0.986

A typical “deep-cycle” battery (used for electric trolling motors for fishing boats) is capable of delivering 12 V and 5 A for a period of 10 hours. How much charge flows through the battery in this interval? How much energy is delivered by the battery?

A coil 4.40 cm in radius, containing 460 turns, is placed in a uniform magnetic field that varies with time according to B=( 1.20x10-2 T/s)t+(2.95x10-5 T/s4 )t¹. The coil is connected to a 680 2 resistor, and its plane is perpendicular to the magnetic field. You can ignore the resistance of the coil.
