Question

a copper conductor of length 10cm and radius 1 5mm
is connected in parallel to an ammeter having a resistance of 0
03ohm find the current in the circuit if the ammeter indicates 0 4A
the resistivity of copper is 1 78 *
10-8

Himanshu · Accepted Answer

Resistance of the copper rod:

As the ammeter and the copper rod are parallel to each other, thus the potential drop across them is equal

a copper conductor of length 10cm and radius 1.5mm is connected in parallel to an ammeter having a resistance of 0.03ohm. find the current in the circuit if the ammeter indicates 0.4A . the resistivity of copper is 1.78 * 10-8 .

a copper conductor of length 10cm and radius 1.5mm is connected in parallel to an ammeter having a resistance of 0.03ohm. find the current in the circuit if the ammeter indicates 0.4A . the resistivity of copper is 1.78 * 10^{-8 .}
