Explanation
Climate finance refers to local, national, or transnational financing drawn from various sources to support climate change mitigation and adaptation.

Q437. Which of the following instruments is used to measure electric current in a circuit?
Explanation
An ammeter is a specialized electrical instrument designed to measure the rate of electric current flowing through a circuit. It is calibrated to provide readings in Amperes, the standard unit of current. To accurately capture the flow of electrons, it must be integrated directly into the circuit path so that the entire current passes through the device for measurement.
Q438. Gilund, a significant regional center of the Banas culture, is situated near which river?
