Question

a) Find the peak voltage in this circuit.

b) If the frequency of the source were adjusted to 80 Hz, would you expect more or less current to flow? Explain why.

2. Two bar magnets are placed on a paper as below. A copper (non-magnetic) wire is placed between them.

a) With NO current flowing through the wire, sketch the magnetic field surrounding these magnets. (sketch on a paper or something!)

b) If a current is now run through the wire in the direction shown, is there a force on the wire? If so, in which direction? Explain your answer.

peak voltage=rms voltage*sqrt(2)=14.14 volts

2)current will be less as capacitive reactance 1/(2*pi*f*C) will increase and as impedance increases,current will decrease.

magnetic field will start from N and end on S.

if a current flows,

force will be in opposite to the magnet.
