Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?
A low voltage supply from which one needs high currents must have very low internal resistance. Why?
How much energy is consumed when a current of 5 amperes flows through the filament (or element) of a heater having resistance of 100 ohms for two hours? Express it in joules.
Calculate the current flowing through a wire of resistance 5 Ω connected to a battery of potential difference 3 V.
A wire has a length of 2.0 m and a resistance of 5.0 Ω. Find the electric field existing inside the wire if it carries a current of 10 A.
Fig. represents the circuit used for the verification of ohm's law. Label the different parts from A and F. State the function of each.
A wire connected to a power supply of 230 V has power dissipation P1. Suppose the wire is cut into two equal pieces and connected parallel to the same power supply. In this case, power dissipation is P2. The ratio of `"P"_2/"P"_1` is
Assertion: The statement of Ohm’s law is K = IR.
Reason: V = IR is the equation which defines resistance.
