Question

Two wires X and Y are of equal length and have equal resistances. If the resistivity of X is more than that of Y which wire is thicket and why ? For the electric circuit given below calculate: (i) Current in each resistor (ii) Total current drawn from the battery and (iii) Equivalent resistance of circuit

Answer 1

Answer:

Two wires X and Y are of equal length and have equal resistances. If the resistivity of X is more than that of Y, which wire is thicker and why ? For the electric circuit given below calculate :

(i) Use above graphs to list word differences between the current in the two cases.

(ii) Name the type of current in two cases

(iii) Identify one source each for these currents.

(iv) What is meant by the statement that "the frequency of current in India is 50 Hz ?" Calculation of electric circuit
