Various amplifier and load combinations are measured as listed below using rms values. For each, find the voltage, current, and power gains (Av, Ai, and Ap, respectively) both as ratios and in dB: a. Vi= 100mV; i=100μA ; vo =10V ; RL= 100Ω
b. Vi= 10μV; i=100nA ; vo =1V ; RL= 10kΩ
c. Vi= 1V; i=1mA ; vo =5V ; RL= 10Ω

An electric kettle is made out of stainless steel, weighs two pounds (when empty) and is equipped with a heating element that consumes 2 kw of electricity. assuming that the water and the kettle are at the same uniform temperature at any moment of time, calculate the shortest possible time to bring 2 quarts of water from room temperature to the onset of boiling
