Why do we have to be careful to protect ammeters? R2^ R, Circuit 2 2) R1 = 100 R2 = 50 R3 = 30 aFind Rsfor both circuits b. Calculate the current in each resistor in each circuit

Explanation / Answer

As per chegg policy I am giving answer to first question.

1) To convert a galvanometer into an ammeter a shunt (low resistance conductor wire) is used in parallel to the galvanometer.

This shunt is vulnerable to high current as it can melt due to high heat hence ammeter is used carefully.
