An AC generator causes 50 Hz current in a circuit containing a 290 Ω resistor, 4.89 µF capacitor, 0.362 H inductor, and switch in series. At time t=0, the switch is closed at an instant when the voltage from the generator is 0 V. We measure the rms current as 41.1 mA. a) Write an expression for the instantaneous voltage (aka, the voltage as a function of time). v(t) = ______ b) Does the voltage lead or lag the current? Explain how you know.  c) Draw a phasor diagram at an instant when the current is zero. Label the phase angle. d) Draw a phasor diagram at an instant when the current is maximum. Label the phase ang

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.
