What are two types of currents?
Direct current and alternating current
What do alternating currents do'?
It is an alternating current that switches its polarity 60 times in a second. 60 Hertz is the frequency that electricity is generated in the U.S.

Who believed it was dangerous to fool around with alternating currents?
Thomas Edison believed it was dangerous to fool around with alternating currents and promoted the use of direct current instead. He was in a bitter rivalry with Nikola Tesla, who championed the use of alternating current for its efficiency over long distances.

How does the frequency of a changing magnetic field compare with the frequency of the alternating voltage that is induced?
A changing magnetic field generates an electric field and alternating currents are accompanied (or caused) by alternating voltages.
What opposes the flow of an electric currents?
Resistance in OMS: In alternating current is is measured in impedance.
