Exercise
A 0.5 0 microfarad capacitor a 20 ohm resistor and a 0.050 H inductor are connected in series across a 25 volt 1,000 Hz power source. Calculate the voltage readings across the capacitance and inductance.
A 40 microfarad capacitor is connected in series with a 40 ohm resistor and connected to a 100 volt 50 Hz alternating current supply.
Draw a circuit diagram of the arrangement
Calculate the impedance in the circuit the current in the circuit and the potential difference across the capacitor.
