The measurement of how fast the current is flowing is the Ampere.
Your current salary is the ammount of money you are earning in your current job, usually expressed as an ammount per annum (per year).
Flowing electricity is called electric current.
It measures current by creating a coil around the current carrying wire. Current flowing in the wire induces a current in the amp-meter proportional to the current flowing in the wire.
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
Current flowing through a device depends on resistance offered by that device.
Alternating current would fit this description.
Yes, a solenoid will still have a magnetic field even if there is no current flowing through it.
A compass needle test will determine whether a current is flowing in the wire.IF the current is flowing the compass needle will deflect from alignment with the wire.
You can measure current - or the lack of current - with an ammeter.
Protection of busbars is mainly done using differential relays. These relays sense current flowing into the bus and current flowing out of the bus. If current in != current flowing out, the relay assumes there is a fault on the bus and trips breakers to isolate the bus.
