The heat developed in a system is proportional to the current through it.

Assertion: current sensitivity of a galvanometer is directly proportional to the current through the coil. Reason: Voltage sensitivity is inversely proportional to voltage.

Assertion current sensitivity of a galvanometer is directley proportionall to the current through the coil. Reason Voltage sensitivity is inversely proportional to voltage.

Heat produced in any resistor is directly proportional to the square of the _____________ passing through the resistor.

A steady current I flows through a wire of radius r, length L and resistivity rho . The current produced heat in the wire. The rate of heat loss in a wire is proportional to its surface area. The steady temperature of the wire is independent of–

Assertion: The specific heat of a gas in an adiabatic process is zero and in an isothermal process is infinite. Reason: Specific heat of a gas is directly proportional to the heat in system and inversely proportional to change in temperature.

Assertion: The division are equaly marked on the scale of AC ammeter. Reason: Heat produced is directely proportional to the current
