Why the current coil of wattmeter has more thikness wire than pressure coil?
Current coil carries the current.
What is current coil and voltage coil?
The current coil is one through which the current of source can pass. This coil is connected in series. The voltage coil is connected parallel to the applied voltage. In the current coil the quantity of current flowing is proportional to the current flowing in load while in the voltage coil, current flowing is proportional to applied supply voltage. The voltage coil current is independent of current flow in load. For a complete understanding, please refer to a watt meter diagram.
What happens to the current in a circuit if one resistance is doubled or halved?
P1 = V I1, Therefore, if P2=0.5*P1, thenI2=0.5*P1/V, or 0.5*I1and if P3=2*P1, thenI3=2*P1/V, or 2*I1In other words, current is proportional to power and inversely proportional to voltage.
What happens when a coil of wire cuts through a magnetic field?
If the magnetic field is fluctuating, or the coil of wire and magnetic field are moving with respect to each other, then a current is induced in the coil of wire. If the two are stationary and the magnetic field is stable, then no current is induced in the coil. However, if there is a current in the coil, from another source, then the coil and the field will exhibit a relative force that will tend to move the coil with respect to the field.
What happens when a magnet is moved towards a coil?
You will generate electricity. As the wire cuts through the magnetic field.As the magnet is moved, there will be an induced electro-motive force (EMF) which can cause a current in the coil. Once the magnet stops moving, the current will go to zero.
What happens when a coil is rotated between two magnets?
The coil will produce an alternating electric current.
What happens if a coil is rotated between two magnets?
The coil will produce an alternating electric current.
What happens to the electric current if the magnet no longer moves in the coil?
The electrical current stops flowing.
Why current becomes halved when load is halved in transformer?
Load halved means the power is halved.Voltage being (assumed) constant, the current is halved. P (Load in Watts)= V x I Hence P/2= V x I/2
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What happens to the circumference if the diameter is halved?
Yes it does. By a factor of 4.
What happens when you multiply a number by 0.5?
It is halved.
What happens to the resistance when length is doubled n area is quadrupled?
It is halved.It is halved.It is halved.It is halved.
What happens to pressure when the temperature and volume is halved?
if kelvin temp is halved, the volume is halved if pressure is constant.
What happens when a electric current is passed through a coil of wires?
You generate a (stronger) magnetic field.
If you double the volume of an object what happens to the density?
It is halved.
What is the difference between current coil and voltage coil?
These terms apply to the coils inside a wattmeter. 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.
