and Answers
Average Value - Answer-0.637x peak value
RMS value - Answer-.707 x Peak Value
Inductance - Answer-Opposes the change of current flow
Self Inductance - Answer-Ability of a conductor to induce voltage in itself when the
current changes
Symbol for inductance - Answer-L
The greater the number of turns the greater the - Answer-Inductance is.
In an inductive circuit - Answer-Voltage leads Current.
Inductive resistance - Answer-2pifl
Capacitor - Answer-Device that stores electric charge
Larger plates will produce a - Answer-Greater Capacitance
Current leads voltage in a - Answer-Capacitive Circuit
Impedance - Answer-Total opposition of current flow
Circuit contains both inductance and resistance the current - Answer-Will lag the voltage
by some angle between zero and 90 degrees
In a circuit containing resistance only - Answer-The circuits are in phase
In a circuit of our capacitance - Answer-The current leads voltage by 90 degrees
In a circuit with both resistance and capacitance - Answer-The current will lead the
voltage by some angle between zero and 90 degrees
True Power - Answer-Power consumed by resistance
Apparent Power - Answer-Product of the source voltage and total current
Reactive Power is - Answer-Always 90 degrees out of phase with true power
