Question

7) Given a timing circuit, you are asked to connect the following components in series. A 6- microfarad capacitor, and a 2002. They car connected with a 30 V voltage source that has angular frequency of 250 rad/s. a) What is the impedance of the entire circuit? b) What is voltage across both the resistor and capacitor? c) Calculate the phase angle d) What quadrant would you find this angle? 8) A resistor is put in a circuit to control the amount of charge that flows through it. In the process of controlling the charge, what will happen to the body of the Resistor? a) It will get hot b) It will remain unchanged invariant) c) It depends on how much charge is going through the circuit
