What is the current in a 12-volt circuit with two 6-ohm resistor connected in parallel?
Two 6-ohm resistors in parallel have a net effective resistance of 3 ohms.With 3 ohms connected across a 12-volt supply, the current is 12/3 = 4 amperes.
A 4000-Ω resistor is connected across 220 V what current will flow?
A 4000-Ω resistor is connected across 220 V will have a current flow of 0.055 A.Ohm's law: Voltage equals Current times Resistance
When the dc motor is connected across an AC supply then?
It depends on the construction of the motor. If the field winding is connected in series with the armaturewinding, the motor is like a universal motor and will probably operate normally. If the field winding is connected in parallel with the armature, the motor will not run, but will draw current, make noise and get hot.
Watt is the current allowed to flow through a bulb?
The current flowing through a bulb is equal to the (voltage across the bulb) divided by the (bulb resistance), and can be expressed in Amperes. The rate at which the bulb dissipates energy is equal to (voltage across the bulb) times (current through the bulb), and can be expressed in watts.
What s the correct calulation for the bulb power on watts which has has a current of 0.5 and the voltage is 220v?
Power is current times voltage, so a current of 0.5 amperes and a voltage of 220v across a bulb will yield a power of 110 watts.

How much current 2.2 Megohm?
"Ohm" and its multiples is not a unit of current."Ampere" and its multiples is.The current through a 2.2-megohm resistance is(the voltage across the resistance)/(2,200,000) amperes .

What does a inductor do when connected across ac supply?
opposes changes in current
Can a wire connected across a battery's terminal produce current?
Yes
What is required for current to flow through an electrical current?
Potential Source connected across a Closed Circuit Path.
How many amperes does a 6 volt DC battery put out?
That will depend on the sum of the load resistance and the internal resistance of the battery (this is true for all power sources, not just 6 volt batteries). Small compact batteries tend to have higher internal resistance and therefore are more limited in the current they can deliver to a given load than larger batteries.
Could a wire connected across a battery's terminals produce a current?
sure whatever?

A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
