What is the current in a parallel circuit which has two resistors (17.2 ohms and 22.4 ohms) and a power source of 6.0 volts?
By Ohm's Law, current is voltage divided by resistance, so a voltage of 6 volts across a resistance of 24 ohms will develop a current of 0.25 amperes.
What is the effect of field current on dc motor?
The field current of a dc motor provides the magnetic field that allows the motor to develop a torque when current flows through the armature..
Slip power in a induction motor?
slip power is a power which is develop by the induced voltage and current in an induction motor
Why add a resistor in a core ground circuit?
It will limit the amount of circulating current that will develop in the core if you have an inadvertent core ground.
Why do the current readings differ for increasing and decreasing values of the incandescent lamp wattages?
While Voltage and Resistance typically remain constant in incandescent lamps: P (Power in Watts) = I (Current in Amperes) times E (Electrostatic energy in Volts [AC and DC]). P=I*E - when P (Watts) goes up so does I (Amps).

How capacitor opposes the change in current?
as a voltage is applied across a capacitor charges accumulate on the plates.due to accumulation of charges,electric field between the plates develop in the direction opposite to the applied field.this field give rise to the potential across the plates.if the plates get completely charged due to the applied voltage i.e if the whole of the charge q=c(capacitance of the capacitors)xv(voltage applied) develops on the plates,then the applied voltage wiil be opposed to an extent that no further charges will induce on it.But in practice,it takes very long time for the capacitor to get completely charged due to the applied voltage..............now coming to ac circuits,having capacitor.......if the frequency of ac applied voltage is less then the voltage will change slowly.due to this at each instant large amount of charge will develop on the plates causing large opposition.vice versa to high frequency applied voltage.
What does 100 watt means?
A watt is a made-up unit of measurement named after James Watt (who helped to develop the steam engine in England). Watts = Volts x Amperes
