In the circuit below, two series combinations of RL (resistor and inductor) and RC (resistor and capacitor) are connected in parallel to an AC source with a variable frequency. Determine the current provided by the AC source in the case of i) a very low frequency ii) and a very high frequency.
The label on the bottom of an electric kettle indicates that it would draw 3.2 A from a 110-V ac wall socket. Calculate the current amplitude for the electric kettle.
What is the frequency of the current found inside of an AC circuit described by the equation 𝐼 = 2.50⋅\cdotsin(300𝑡), where 𝐼 is in amperes and 𝑡 is in seconds?
