Let the resistance of an electrical component remains constant while the potential difference across the two ends of the component decreases to half of its former value. What change will occur in the current through it?

What is the potential difference between two points in the electric field? Name its SI unit.

If the potential difference across the ends of a conductor is 1 volt and the current flowing through the conductor is 1 ampere, the resistance of the conductor?

The current flowing through a conductor and the potential difference across it two ends are as per readings of the ammeter and voltmeter shown below. The resistance of the conductor would be

Potential difference between two given points 5, cm apart, is 20V. What is the value of electric field?

When an electric device X is connected to a 220 volt, 50 hertz a.c. supply, the current is 0.5 amp, and is in same phase as the applied voltage. When another device Y is connected to the same supply, the electric current is again 0.5amp, but it leads the potential difference by pi//2 . When X and Y are connected in serices across the same source, what will be the current ?

Two wire A & B are of the same metal and are of same length have area of cross section in the ratio of 2:1 If the same potential difference is applied across each wire. What will be the ratio of the current flowing through the wires A & B ?

The middle point of a conductor is earthed and its ends are maintained at a potential difference of 220V. What is the potential at two ends and at the middle point?

An ideal inductor of 1 H is connected across a resistance of 100 ohm as shown in the figure. What is the potential difference across the 100 ohm resistance, when the current has attained a steady value?
