what is ohm's law ? what is galvanometer
Answers
Answer:Ohm’s law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm’s law is V=IR. This relationship between current, voltage, and relationship was discovered by German scientist Georg Simon Ohm. Let us learn more about Ohms Law, Resistance, and its applications.
A galvanometer is a type of ammeter. It is an instrument for detecting and measuring electric current.
Answer:
OHM'S LAW:
If physical conditions like temperature etc. of a conductor are kept unchanged the strength of current flowing through it is directly proportional to the potential difference across its ends.
Galvanometer is a device used for detecting the flow of current in an electric circuit .
