Question

6. How? explain for the following:
a) Ammeter is connected b) Voltmeter is connected
c) Fuse works
d) To verify Ohm's law​

Answer 1

a)ammeter is used to detect the current in the line

b)voltmeter is connected to detect or determine the voltage in the line

c)in homes ordinary fuse is used to stop the short circuit in the whole line if short circuit occurs the wires of the fuses can be broken but no effect shown on the line

Ohm's law is V is equals to IR where V is a potential and R is the resistance of the proportionality constant and I is the current flowing in the wire
