WHAT ENERGY USED IN A BATTERY POWERED FLASHLIGHT?
Electricity is used. It is stored in the form of DC voltage. DC is direct current which is not what is used in your home. DC is used in storage batteries. AC or alternating current is what is used to power your home.
What is DC ammeter?
Instrument used to measure dc current
Why DC is used in battery's?
dc in battery stands for direct current .ac is alternating current.
Why transformer can not be used in dc supply?
The transformer cannot be used in the DC supply because it keeps on alternating its current, whereas the DC supply current should be constant.
Are diodes only used in a dc circuit?
There are lots of diodes - a "diode" is simply a device that has two electrical connections.If you refer specifically to the rectifying diode, it is used to convert AC current to DC current - so, it is used in a circuit that has BOTH AC and DC.
Where do you use DC current?
DC current is mainly used in electronic component i.e. computer etc
What current types are diodes used in?
Direct Current or DC
What type of current is used in battery?
DC direct current
Why pmmc used for DC only?
Because in the coil DC current follow easly and pmmc meter is making with coil and AC current is not follow in coil so we used the pmmc only fpr DC current.
Why DC supply is used in control circuit?
dc supply is used for control circuit because dc current is an independent source .
What is the type of current used in batteries?
DC
Does the galvanometer measures AC and DC current?
It is used to detect very small DC currents only. For AC signals Detectors are used.
