we often say "a current is going through the wire " What goes through the wire,the charge or the current ?

The current flowing through the zener diode in fig is-

A potential difference of 10 V is needed to make a current of 0.02 A flow through a wire. What potential difference is needed to make a current of 250 mA to flow through the same wire?

When no current is passed through a conductor,

What will be the number of electron passing through a heater wire in one minute, if it carries a current of 8A

If an A.C. current of frequency 50 Hz is flowing through a conducting wire, then how many time does the current becomes zero in one second ?

Assertion: Through the same current flows through the line wires and the filament of the bulb but heat produced in the filament is much higher than that in line wires. Reason: The filament of bulbs is made of a material of high resistance and high melting point.

Consider a current carrying wire (current I) in the shape of a circle. Note that as the current progresses along the wire, the direction of J (current density) changes in an exact manner, while the current I remain unaffected. The agent that is essentially responsible for is

The current is flowing through solenoid, then solenoid acting as what ?

A compass needle is placed near a current - carrying straight wire . State your observation when the current in the wire is increased . Give reason .

The same mass of copper is drawn into two wires 2 mm and 4mm thick. The two wires are connected in series and current is passed through them. The ratio of heat produced in the two wires is
